The beauty of data visualization | David McCandless

Prevodilac: Mirna Radin-Sabadoš Lektor: Sandra Gojic

It feels like we're all suffering

Čini se da smo svi izloženi

from information overload or data glut.

bombardovanju podacima i da smo preopterećeni informacijama.

And the good news is there might be an easy solution to that,

Dobro je što tome svemu možda i možemo lako doskočiti

and that's using our eyes more.

tako što ćemo se više oslanjati na svoj vid.

So, visualizing information, so that we can see

Dakle, vizualizacijom podataka, možemo da vidimo

the patterns and connections that matter

sheme i veze koje su od značaja,

and then designing that information so it makes more sense,

da preoblikujemo informacije tako da imaju više smisla

or it tells a story,

ili da ispričamo neku priču

or allows us to focus only on the information that's important.

ili da se jednostavno usredsredimo samo na informacije koje su nam važne.

Failing that, visualized information can just look really cool.

Osim toga, vizualizivane informacije ponekad izgledaju veoma lepo.

So, let's see.

Hajde da pogledamo.

This is the $Billion Dollar o-Gram,

Ovo je Billion Dollar Gram (dijagram milijardu dolara)

and this image arose

i ta je slika nastala kao posledica

out of frustration I had

frustracije koju sam osećao

with the reporting of billion-dollar amounts in the press.

kad bih u štampi pisao o iznosima od milijardu dolara.

That is, they're meaningless without context:

Ti podaci su besmisleni ako nisu u kontekstu.

500 billion for this pipeline,

500 milijardi za ovaj cevovod.

20 billion for this war.

20 milijardi za onaj rat.

It doesn't make any sense, so the only way to understand it

Nema nikakvog smisla, i jedini način da išta razumete

is visually and relatively.

jeste da se podatak prikaže vizuelno i u odnosu na nešto.

So I scraped a load of reported figures

I tako sam skupio gomilu brojki o kojima se izveštava

from various news outlets

iz različitih novinskih agencija

and then scaled the boxes according to those amounts.

i prikazao ih pravougaonicima čija veličina odgovara tim iznosima.

And the colors here represent the motivation behind the money.

Boje ovde predstavljaju motivaciju koja stoji iza novca.

So purple is "fighting,"

Ljubičasta predstavlja ratovanje,

and red is "giving money away," and green is "profiteering."

a crvena doniranje novca, dok je zelena gomilanje zarade.

And what you can see straight away

I odmah se može videti

is you start to have a different relationship to the numbers.

da postoji drugačiji odnos prema brojevima.

You can literally see them.

Bukvalno ih vidite.

But more importantly, you start to see

Ali, što je još važnije, počinjete da uviđate

patterns and connections between numbers

sheme i veze među brojevima

that would otherwise be scattered across multiple news reports.

koje bi inače ostale nezapažene u moru novinskih izveštaja.

Let me point out some that I really like.

Pokazaću vam neke koje mi se veoma dopadaju.

This is OPEC's revenue, this green box here --

Ovo je prihod OPEKa, ovaj zeleni pravougaonik -

780 billion a year.

780 milijardi godišnje.

And this little pixel in the corner -- three billion --

A ovaj mali piksel u uglu - tri milijarde -

that's their climate change fund.

to je njihov fond za borbu protiv klimatskih promena.

Americans, incredibly generous people --

Amerikanci, neverovatno darežljivi ljudi -

over 300 billion a year, donated to charity every year,

doniraju u dobrotvorne svrhe preko 300 milijardi godišnje,

compared with the amount of foreign aid

u poređenju sa iznosom inostrane pomoći

given by the top 17 industrialized nations

koja dolazi od 17 najrazvijenijih zemalja

at 120 billion.

što iznosi 120 milijardi.

Then of course,

A onda, naravno,

the Iraq War, predicted to cost just 60 billion

rat u Iraku, za koji su predviđali da će da košta 60 milijardi

back in 2003.

2003. godine.

And it mushroomed slightly. Afghanistan and Iraq mushroomed now

Malčice je premašio očekivanja. Avganistan je narastao do

to 3,000 billion.

3000 milijardi danas.

So now it's great

Sada je to izvanredno

because now we have this texture, and we can add numbers to it as well.

jer sada imamo teksturu, i možemo joj dodavati brojeve.

So we could say, well, a new figure comes out ... let's see African debt.

Mogli bismo reći, na primer, nova brojka se pomalja ... da pogledamo afrički dug.

How much of this diagram do you think might be taken up

Koju površinu ovog dijagrama mislite da zauzima

by the debt that Africa owes to the West?

dugovanje Afrike prema zapadu?

Let's take a look.

Hajde da pogledamo.

So there it is:

Evo ga.

227 billion is what Africa owes.

227 milijardi duguje Afrika.

And the recent financial crisis,

A ova poslednja finansijska kriza -

how much of this diagram might that figure take up?

šta mislite koliko ovog dijagrama može zauzeti ta cifra?

What has that cost the world? Let's take a look at that.

Koliko je to koštalo ceo svet? Hajde da to pogledamo.

Dooosh -- Which I think is the appropriate sound effect

Plus! Mislim da je to odgovarajući zvučni efekat

for that much money:

za tu količinu novca.

11,900 billion.

11900 milijardi.

So, by visualizing this information,

Pretvaranjem informacije u sliku,

we turned it into a landscape

pretvorili smo je u pejzaž

that you can explore with your eyes,

koji možete istraživati gledajući ga,

a kind of map really, a sort of information map.

to postaje neka vrsta mape, mapa informacija.

And when you're lost in information,

A kada se ne snalazite u informacijama,

an information map is kind of useful.

mapa informacija je nekako korisna.

So I want to show you another landscape now.

Prikazaću vam još jedan pejzaž.

We need to imagine what a landscape

Treba da zamislimo kakav je to pejzaž

of the world's fears might look like.

koji bi oslikavao strahove čovečanstva.

Let's take a look.

Pogledajmo.

This is Mountains Out of Molehills,

Ovo su planine i brežuljci

a timeline of global media panic.

vremenska osa globalne panike.

(Laughter)

(smeh)

So, I'll label this for you in a second.

Obeležiću vam ovo začas.

But the height here, I want to point out,

Ali ovo uzvišenje, naročito hoću da istaknem,

is the intensity of certain fears

jeste intenzitet određenih strahova,

as reported in the media.

kako o njima izveštavaju mediji.

Let me point them out.

Pokazaću vam.

So this, swine flu -- pink.

Ovo - svinjski grip - ružičasto.

Bird flu.

Ptičiji grip.

SARS -- brownish here. Remember that one?

SARS - braonkasto, ovde. Sećate li se toga?

The millennium bug,

Milenijumska buba -

terrible disaster.

užasna katastrofa.

These little green peaks

ovi mali zeleni vrhovi

are asteroid collisions.

predstavljaju sudare asteroida.

(Laughter)

(smeh)

And in summer, here, killer wasps.

A u leto, ovde, pčele ubice.

(Laughter)

(smeh)

So these are what our fears look like

Ovako izgledaju naši strahovi

over time in our media.

u medijima u određenom vremenskom periodu.

But what I love -- and I'm a journalist --

Ali ono što mi se posebno dopada - a ja sam novinar -

and what I love is finding hidden patterns; I love being a data detective.

i naročito uživam u tome da pronalazim skrivene sheme; volim da budem detektiv za podatke.

And there's a very interesting and odd pattern hidden in this data

U ovim se podacima krije naročito neobična i zanimljiva shema

that you can only see when you visualize it.

koju možete primetiti samo ako je vizualizujete.

Let me highlight it for you.

Obeležiću je.

See this line, this is a landscape for violent video games.

Pogledajte ovu liniju. Ovo je model koji predstavlja nasilne video igre.

As you can see, there's a kind of odd, regular pattern in the data,

Kao što vidite, postoji naročito, pravilno ponavljanje u podacima

twin peaks every year.

vršne vrednosti dva puta godišnje

If we look closer, we see those peaks occur

Ako pogledamo detaljnije, videćemo da se vršne vrednosti

at the same month every year.

postižu istog meseca svake godine.

Why?

Zašto?

Well, November, Christmas video games come out,

Pa, u novembru se puštaju u prodaju Božićne video igre,

and there may well be an upsurge in the concern about their content.

i moguće je da zabrinutost raste zbog njihovog sadržaja.

But April isn't a particularly massive month

Ali april nije mesec naročito opterećen

for video games.

video igrama

Why April?

Zbog čega april?

Well, in April 1999 was the Columbine shooting,

Pa, u aprilu 1999. dogodila se pucnjava u Kolombajnu.

and since then, that fear

i otada, toga se straha podsećamo

has been remembered by the media

preko medija

and echoes through the group mind gradually through the year.

i on odzvanja našom kolektivnom svešću preko godine.

You have retrospectives, anniversaries,

Imate retrospektive, godišnjice,

court cases, even copy-cat shootings,

sudske procese, čak i druge pucnjave po uzoru na ovu

all pushing that fear into the agenda.

što sve taj strah stavlja u prvi plan.

And there's another pattern here as well. Can you spot it?

A postoji još jedna shema u tome. Da li je uočavate?

See that gap there? There's a gap,

Vidite ovaj razmak? Tu postoji nepravilnost

and it affects all the other stories.

koja utiče na sve druge priče.

Why is there a gap there?

Zašto ovde imamo razmak?

You see where it starts? September 2001,

Vidite li kada počinje? Septembar 2001,

when we had something very real

kada se pojavilo nešto veoma stvarno

to be scared about.

čega se trebalo plašiti.

So, I've been working as a data journalist for about a year,

Kao novinar sam istraživao podatke oko godinu dana,

and I keep hearing a phrase

i stalno sam slušao fraze

all the time, which is this:

slične ovoj:

"Data is the new oil."

"Podaci su nafta današnjice."

Data is the kind of ubiquitous resource

A podaci i jesu sveprisutni resurs

that we can shape to provide new innovations and new insights,

koji možemo oblikovati da bismo stvorili nove izume ili otvorili neke nove poglede na svet

and it's all around us, and it can be mined very easily.

i nalaze se svuda oko nas i veoma lako se mogu vaditi.

It's not a particularly great metaphor in these times,

U današnje vreme to i nije naročito uspela metafora,

especially if you live around the Gulf of Mexico,

naročito ako živite u blizini Meksičkog zaliva,

but I would, perhaps, adapt this metaphor slightly,

zato bih je malo prilagodio,

and I would say that data is the new soil.

i rekao bih da su podaci plodno tlo današnjice.

Because for me, it feels like a fertile, creative medium.

Jer, za mene, to i jeste plodan, kreativni medijum.

Over the years, online,

Vremenom smo onlajn

we've laid down

pohranili

a huge amount of information and data,

ogromne količine informacija i podataka,

and we irrigate it with networks and connectivity,

i negovali smo ih stvaranjem mreža i povezivanjem,

and it's been worked and tilled by unpaid workers and governments.

a o njima su se starali i sa njima su radili volonteri i vlade.

And, all right, I'm kind of milking the metaphor a little bit.

I, slažem se, možda malo preterujem,

But it's a really fertile medium,

Ali to je zaista veoma plodan medijum,

and it feels like visualizations, infographics, data visualizations,

i čini se da vizualizacije, grafički prikazi, prikazi podataka

they feel like flowers blooming from this medium.

naprosto cvetaju u tom medijumu.

But if you look at it directly,

Ali ako pogledamo neposredno,

it's just a lot of numbers and disconnected facts.

to je samo masa nepovezanih podataka.

But if you start working with it and playing with it in a certain way,

Ali ako krenete da se sa njima igrate na određeni način,

interesting things can appear and different patterns can be revealed.

mogu da se pojave zanimljive stvari i mogu da se otkriju različite sheme.

Let me show you this.

Pokazaću vam.

Can you guess what this data set is?

Šta mislite šta predstavljaju ovi podaci?

What rises twice a year,

Šta je to čije vrednosti skaču dva puta godišnje,

once in Easter

jednom na Uskrs

and then two weeks before Christmas,

a onda dve nedelje pred Božić,

has a mini peak every Monday,

pokazuje mali skok svakog ponedeljka

and then flattens out over the summer?

a onda potpuno padne preko leta.

I'll take answers.

Slušam odgovore.

(Audience: Chocolate.) David McCandless: Chocolate.

(Publika: Čokolada.) Dejvid Mekkendls: Čokolada.

You might want to get some chocolate in.

Možete i čokoladu dodati.

Any other guesses?

Još neko?

(Audience: Shopping.) DM: Shopping.

(Publika: Kupovina.) DM: Kupovina.

Yeah, retail therapy might help.

Jeste, terapija u maloprodaji možda pomogne.

(Audience: Sick leave.)

(Publika: Bolovanje.)

DM: Sick leave. Yeah, you'll definitely want to take some time off.

DM: Bolovanje. Jeste, sasvim ćete sigurno poželeti slobodne dane.

Shall we see?

Da pogledamo?

(Laughter)

(Smeh)

(Applause)

(Aplauz)

So, the information guru Lee Byron and myself,

Informacije koje vidite ovde, sakupili smo Li Bajron i ja

we scraped 10,000 status Facebook updates

iz 10000 ažuriranja statusa na Fejsbuku

for the phrase "break-up" and "broken-up"

tražili smo frazu "raskid" ili "raskinuli"

and this is the pattern we found --

i ovo je shema do koje smo došli -

people clearing out for Spring Break,

ljudi prave veliko spremanje pred prolećni raspust,

(Laughter)

(Smeh)

coming out of very bad weekends on a Monday,

izlaze iz groznih vikenda ponedeljkom,

being single over the summer,

preko leta nisu u vezi.

and then the lowest day of the year, of course: Christmas Day.

A onda, tu je najniža vrednost u toku godine koju beležimo na Božić.

Who would do that?

Ko bi to uradio?

So there's a titanic amount of data out there now,

Postoji nezamislivo velika količina podataka, kao

unprecedented.

nikada ranije.

But if you ask the right kind of question,

Ali ako postavite pravo pitanje,

or you work it in the right kind of way,

ili ako podatke obradite na pravi način,

interesting things can emerge.

dolazite do veoma zanimljivih stvari.

So information is beautiful. Data is beautiful.

U informacijama nalazimo lepotu. Podaci kriju lepotu.

I wonder if I could make my life beautiful.

Pitam se da li bih mogao da i sebi slične prikažem lepima.

And here's my visual C.V.

Evo moje vizualizovane biografije.

I'm not quite sure I've succeeded.

Nisam siguran da sam u tome uspeo.

Pretty blocky, the colors aren't that great.

Prilično je nezgrapno. Ni boje nisu baš nešto.

But I wanted to convey something to you.

Ali hteo sam nešto da vam ispričam.

I started as a programmer,

Počeo sam kao programer,

and then I worked as a writer for many years, about 20 years,

a onda sam niz godina radio kao pisac, skoro 20 godina,

in print, online and then in advertising,

prvo u štampanom medijumu, onlajn a onda i u reklamnoj industriji,

and only recently have I started designing.

i tek sam nedavno počeo da radim dizajn.

And I've never been to design school.

A nikada nisam išao u školu za dizajn.

I've never studied art or anything.

Niti sam studirao umetnost.

I just kind of learned through doing.

Jednostavno sam učio kroz rad.

And when I started designing,

I kada sam počeo da radim dizajn,

I discovered an odd thing about myself.

otkrio sam neke neobične stvari o sebi.

I already knew how to design,

Već sam znao kako se to radi,

but it wasn't like I was amazingly brilliant at it,

mada ne mogu reći da sam postigao neke izvanredne rezultate

but more like I was sensitive

pre bih rekao da sam imao osećaj

to the ideas of grids and space

za prostornost i za modularno predstavljanje prostora

and alignment and typography.

za tipografiju i za poravnavanje sloga strane.

It's almost like being exposed

Kao da je izloženost tom

to all this media over the years

medijumu toliko mnogo godina

had instilled a kind of dormant design literacy in me.

u meni probudilo neku pismenost za dizajn koje nisam bio svestan.

And I don't feel like I'm unique.

Ne mislim da sam jedinstveni slučaj.

I feel that everyday, all of us now

Osećam da smo svakoga dana, svi mi

are being blasted by information design.

zatrpani dizajnom informacija.

It's being poured into our eyes through the Web,

Izliva se u naše oči kroz Mrežu,

and we're all visualizers now;

i svi se oslanjamo na vizualizaciju;

we're all demanding a visual aspect

svi zahtevamo da informacije

to our information.

sadrže vizuelnu komponentu.

There's something almost quite magical about visual information.

A u vizuelnoj informaciji ima nečeg čarobnog.

It's effortless, it literally pours in.

Dešava se bez napora; bukvalno se izliva.

And if you're navigating a dense information jungle,

Ako se krećete kroz teško prohodnu džunglu informacija,

coming across a beautiful graphic

kad naiđete na neke izvanredne crteže

or a lovely data visualization,

ili na očaravajuće vizualizacije podataka,

it's a relief, it's like coming across a clearing in the jungle.

to predstavlja olakšanje, kao da ste na tom neprohodnom terenu naišli na čistinu.

I was curious about this, so it led me

Mene je radoznalost povela ka

to the work of a Danish physicist

radovima danskog fizičara

called Tor Norretranders,

po imenu Tor Noretranders,

and he converted the bandwidth of the senses into computer terms.

koji je preveo opseg čula u računarsku terminologiju.

So here we go. This is your senses,

Evo ga. Ovo su vaša čula,

pouring into your senses every second.

i ono što primate čulima svake sekunde.

Your sense of sight is the fastest.

Čulo vida je najbrže.

It has the same bandwidth as a computer network.

Ima istu brzinu kao i računarska mreža.

Then you have touch, which is about the speed of a USB key.

Onda je tu dodir, čija je brzina slična brzini USB priključka.

And then you have hearing and smell,

Potom dolaze sluh i njuh,

which has the throughput of a hard disk.

čija je brzina ekvivalentna brzini hard-diska.

And then you have poor old taste,

I na kraju imate bedno čulo ukusa,

which is like barely the throughput of a pocket calculator.

koje jedva da može da parira brzini digitrona.

And that little square in the corner, a naught .7 percent,

A ovaj malecki kvadratić, 0,7 posto,

that's the amount we're actually aware of.

to je količina podataka kojih smo zapravo svesni.

So a lot of your vision --

Tako da veliki deo vizuelnog -

the bulk of it is visual, and it's pouring in.

najveći deo ovih informacija je vizuelnog tipa, i jednostavno se uliva.

It's unconscious.

Toga nismo ni svesni.

The eye is exquisitely sensitive

Dok je oko izuzetno osetljivo

to patterns in variations in color, shape and pattern.

na varijacije u boji, obliku i uzorku.

It loves them, and it calls them beautiful.

Dopadaju mu se i smatra ih lepim.

It's the language of the eye.

To je jezik oka.

If you combine the language of the eye with the language of the mind,

A ako kombinujete jezik oka i jezik uma,

which is about words and numbers and concepts,

koji se sastoji od reči, brojeva i pojmova,

you start speaking two languages simultaneously,

govorite dva jezika istovremeno,

each enhancing the other.

i oni jedan drugog upotpunjuju.

So, you have the eye, and then you drop in the concepts.

Imate oko, i sada dodajete pojmove.

And that whole thing -- it's two languages

I sve skupa - ta dva jezika

both working at the same time.

deluje istovremeno.

So we can use this new kind of language, if you like,

Ovaj novi jezik možemo koristiti, na primer,

to alter our perspective or change our views.

da promenimo ugao gledanja ili svoja stanovišta.

Let me ask you a simple question

Postaviću vam jednostavno pitanje

with a really simple answer:

na koje je jednostavno odgovoriti.

Who has the biggest military budget?

Ko ima najveći vojni budžet?

It's got to be America, right?

Mora biti da je Amerika?

Massive. 609 billion in 2008 --

Ogroman je. 609 milijardi 2008 -

607, rather.

zapravo 607.

So massive, in fact, that it can contain

Toliko je veliki da zapravo sadrži

all the other military budgets in the world inside itself.

vojne budžete svih drugih zemalja na svetu.

Gobble, gobble, gobble, gobble, gobble.

Žder, žder, žder...

Now, you can see Africa's total debt there

Ovde vidite ukupni dug Afrike

and the U.K. budget deficit for reference.

i budžetski deficit Velike Britanije radi poređenja.

So that might well chime

U tom smislu može se reći

with your view that America

da Amerika

is a sort of warmongering military machine,

u određenom smislu investira u ratovanje, u vojnu mašineriju,

out to overpower the world

s namerom da nadvlada sve na svetu

with its huge industrial-military complex.

svojim ogromnim vojno-industrijskim kompleksom.

But is it true that America has the biggest military budget?

Ali da li je zaista tako, da li Amerika ima najveći vojni budžet?

Because America is an incredibly rich country.

To je nezamislivo bogata zemlja.

In fact, it's so massively rich

Toliko je ogromno njeno bogatstvo

that it can contain the four other

da sadrži čak četiri ekonomije

top industrialized nations' economies

vodećih industrijskih nacija

inside itself, it's so vastly rich.

toliko je nezamislivo bogata.

So its military budget is bound to be enormous.

Srazmerno tome, i vojni budžet mora biti ogroman.

So, to be fair and to alter our perspective,

Da bismo bili pošteni, i da bismo sve sagledali i iz druge perspektive,

we have to bring in another data set,

moramo da uvedeo još jedan set podataka,

and that data set is GDP, or the country's earnings.

a to je bruto nacionalni dohodak, ili ono što zemlja zarađuje.

Who has the biggest budget as a proportion of GDP?

Čiji je budžet najveći u odnosu na BND?

Let's have a look.

Da pogledamo.

That changes the picture considerably.

Slika se značajno izmenila.

Other countries pop into view that you, perhaps, weren't considering,

I druge zemlje, koje nismo uzimali u razmatranje dolaze u prvi plan.

and American drops into eighth.

a Amerikanci padaju na osmo mesto.

Now you can also do this with soldiers.

Isto to možemo uraditi sa brojem vojnika.

Who has the most soldiers? It's got to be China.

Ko ima najviše vojnika? Mora biti da je to Kina.

Of course, 2.1 million.

Naravno, 2,1 milion.

Again, chiming with your view

I opet, u skladu sa pretpostavkom

that China has a militarized regime

da je Kina zemlja vojnog režima

ready to, you know, mobilize its enormous forces.

spreman da u svakom trenutku mobilizira svoje snage.

But of course, China has an enormous population.

Ali ne zaboravimo da Kina ima ogroman broj stanovnika.

So if we do the same,

Ako opet uradimo poređenje,

we see a radically different picture.

vidimo da se slika iz korena menja.

China drops to 124th.

Kina pada na 124. mesto.

It actually has a tiny army

Zapravo ima minijaturnu vojsku

when you take other data into consideration.

kada se i drugi podaci uzmu u obzir.

So, absolute figures, like the military budget,

Apsolutne vrednosti, kao vojni budžet,

in a connected world,

u umreženom svetu,

don't give you the whole picture.

ne pružaju uvid u celu sliku.

They're not as true as they could be.

Nisu istinite u onoj meri u kojoj se to očekuje.

We need relative figures that are connected to other data

Potrebno nam je upoređivanje sa drugim podacima

so that we can see a fuller picture,

da sagledamo celu sliku,

and then that can lead to us changing our perspective.

i da tako promenimo ugao gledanja.

As Hans Rosling, the master,

Kao što kaže Hans Rosling, vrhunski stručnjak,

my master, said,

moj mentor,

"Let the dataset change your mindset."

"Dozvolite da pogled na podatke promeni vaš pogled na svet."

And if it can do that, maybe it can also change your behavior.

I ako se to dogodi, možda će se promeniti i vaše ponašanje.

Take a look at this one.

Pogledajte ovo.

I'm a bit of a health nut.

Ja sam pomalo zaluđenik zdravim životom.

I love taking supplements and being fit,

Obožavam dodatke prehrani i volim da sam u dobroj kondiciji,

but I can never understand what's going on in terms of evidence.

ali mi nikad nije bilo jasno šta se tu dešava što se može dokazati.

There's always conflicting evidence.

Dokazi su uvek kontradiktorni.

Should I take vitamin C? Should I be taking wheatgrass?

Treba li da uzimam vitamin C? Da li da jedem pšenične klice?

This is a visualization of all the evidence

Ovo je vizualizacija svih dokaza

for nutritional supplements.

koji su u vezi sa dodacima prehrani.

This kind of diagram is called a balloon race.

Ovaj dijagram se zove "nadmetanje balona".

So the higher up the image,

Što je slika na višem položaju,

the more evidence there is for each supplement.

ima više dokaza da taj dodatak deluje.

And the bubbles correspond to popularity as regards to Google hits.

A mehurići predstavljaju popularnost u odnosu na Guglove rezultate pretraživanja.

So you can immediately apprehend

Odmah se vidi odnos

the relationship between efficacy and popularity,

efikasnosti i popularnosti

but you can also, if you grade the evidence,

ali isto tako, dokaze možemo da gradiramo,

do a "worth it" line.

u niz po tome kakav im je učinak.

So supplements above this line are worth investigating,

tako iznad ove crte imamo one koje ima smisla istraživati,

but only for the conditions listed below,

ali samo u odnosu na uslove postavljene dole.

and then the supplements below the line

A onda dodaci koji su ispod crte

are perhaps not worth investigating.

pripadaju grupi koju možda nema smisla istraživati.

Now this image constitutes a huge amount of work.

Ovaj prikaz predstavlja ogroman napor u obradi podataka.

We scraped like 1,000 studies from PubMed,

Pregledali smo preko 1000 studija sa PubMed-a,

the biomedical database,

biomedicinske baze podataka,

and we compiled them and graded them all.

i sve smo ih sakupili i gradirali.

And it was incredibly frustrating for me

A za mene je to bilo neverovatno naporno

because I had a book of 250 visualizations to do for my book,

jer sam imao knjigu sa 250 vizualizacija koje je trebalo obraditi za knjigu,

and I spent a month doing this,

i proveo sam mesece u tom poslu,

and I only filled two pages.

a ispunio sam tek dve stranice.

But what it points to

Ali, to sve ukazuje

is that visualizing information like this

da je vizualizacija podataka

is a form of knowledge compression.

oblik njihove kompresije.

It's a way of squeezing an enormous amount

To je način da se ogromna količina

of information and understanding

informacija i tumačenja

into a small space.

sabije u veoma malo prostora.

And once you've curated that data, and once you've cleaned that data,

I kada se ti podaci pročiste i urede,

and once it's there,

i kada se prikažu na ovaj način,

you can do cool stuff like this.

sa njima se može raditi mnogo zanimljivih stvari.

So I converted this into an interactive app,

Ovo sam konvertovao u interaktivnu aplikaciju,

so I can now generate this application online --

i sada mogu da je pokrenem onlajn -

this is the visualization online --

ovo je vizualizacija onlajn -

and I can say, "Yeah, brilliant."

i mogu da kažem, "Jupi, izvanredno."

So it spawns itself.

Ona samu sebe generiše.

And then I can say, "Well, just show me the stuff

I sad mogu da kažem, "Pa, samo mi pokaži materijal

that affects heart health."

koji govori o uticaju na srce."

So let's filter that out.

Hajde da to izdvojimo.

So heart is filtered out, so I can see if I'm curious about that.

Srce smo izdvojili, i ako me to zanima.

I think, "No, no. I don't want to take any synthetics,

Pomisliću, "Ne, ne. Neću sintetičke proizvode.

I just want to see plants and --

Hoću da vidim samo biljke -

just show me herbs and plants. I've got all the natural ingredients."

prikaži mi samo bilje i trave. Trebaju mi samo prirodni sastojci."

Now this app is spawning itself

Evo, aplikacija samu sebe generiše

from the data.

iz podataka.

The data is all stored in a Google Doc,

Podaci su pohranjeni u Gugl dokumentima,

and it's literally generating itself from that data.

i bukvalno se ovo samo od sebe generiše iz tih podataka.

So the data is now alive; this is a living image,

Podaci su oživeli; ovo je živa slika,

and I can update it in a second.

i mogu da je ažuriram u trenu.

New evidence comes out. I just change a row on a spreadsheet.

Pojaviće se novi dokazi - i ja ću samo promeniti jedan red u tabeli.

Doosh! Again, the image recreates itself.

Pljus! Opet, slika se sama obnavlja.

So it's cool.

To je jako zgodno.

It's kind of living.

I predstavlja oblik života.

But it can go beyond data,

Ali može da dosegne i dalje od podataka,

and it can go beyond numbers.

i dalje od brojki.

I like to apply information visualization

I dopada mi se da primenjujem vizualizaciju informacija

to ideas and concepts.

na ideje i pojmove.

This is a visualization

Ovo je vizualizacija

of the political spectrum,

političkog spektra,

an attempt for me to try

u pokušaju da razumem

and understand how it works

kako to funkcioniše

and how the ideas percolate down

i kako ideje iz vlade

from government into society and culture,

dolaze u društvo i u kulturu,

into families, into individuals, into their beliefs

u porodice, u glave pojedinaca, u njihova uverenja

and back around again in a cycle.

i odatle se vraćaju u krug.

What I love about this image

U ovoj slici posebno smatram vrednim

is it's made up of concepts,

to što je sačinjena od pojmova,

it explores our worldviews

i istražuje naše poglede na svet

and it helps us -- it helps me anyway --

i pomaže nam - barem meni pomaže -

to see what others think,

da sagledam šta drugi misle,

to see where they're coming from.

da shvatim njihova stanovišta,

And it feels just incredibly cool to do that.

a to je odličan osećaj.

What was most exciting for me

Najuzbudljivije u postupku

designing this

stvaranja ove slike

was that, when I was designing this image,

za mene je bilo

I desperately wanted this side, the left side,

to što sam očajnički sebe želeo da stavim na ovu stranu, na levu stranu,

to be better than the right side --

i hteo sam da ona bude bolja od desne strane -

being a journalist, a Left-leaning person --

jer sam takav novinar - leve orijentacije -

but I couldn't, because I would have created

ali nisam mogao to da izvedem, jer bih kreirao

a lopsided, biased diagram.

pristrasan dijagram.

So, in order to really create a full image,

Tako da bih kreirao pravu sliku,

I had to honor the perspectives on the right-hand side

Morao sam da poštujem i perspektivu desne strane

and at the same time, uncomfortably recognize

a istovremeno, morao sam da s nelagodom priznam

how many of those qualities were actually in me,

da mnoge osobine i sam posedujem,

which was very, very annoying and uncomfortable.

što može biti veoma neprijatno.

(Laughter)

(Smeh)

But not too uncomfortable,

No, nije previše neprijatno,

because there's something unthreatening

jer svakako nas manje ugrožava

about seeing a political perspective,

posmatranje političke opcije,

versus being told or forced to listen to one.

nego situacija u kojoj nam se to sve saopštava usmeno

You're capable of holding conflicting viewpoints

Ovako, zapravo, možemo da sagledamo sukobljene perspektive

joyously when you can see them.

sa radošću, u situaciji u kojoj ih gledate.

It's even fun to engage with them

Čak može biti i veoma zanimljivo proučavati ih

because it's visual.

jer su predstavljene vizuelno.

So that's what's exciting to me,

Smatram da je to veoma uzbudljivo,

seeing how data can change my perspective

posmatrati kako podaci menjaju moju perspektvu

and change my mind midstream --

i menjati svoje mišljenje u tom procesu -

beautiful, lovely data.

izvanredni, divni podaci.

So, just to wrap up,

I za kraj,

I wanted to say

hteo sam da kažem

that it feels to me that design is about solving problems

da mi se čini da se i dizajn bavi rešavanjem problema

and providing elegant solutions,

i pronalaženjem elegantnih rešenja.

and information design is about

A dizajn informacija

solving information problems.

bavi se rešavanjem problema informacija.

It feels like we have a lot of information problems

A čini se da imamo mnogo problema sa informacijama

in our society at the moment,

u našem društvu,

from the overload and the saturation

koji je posledica preopterećenosti i zasićenja

to the breakdown of trust and reliability

ili gubitka poverenja i pouzdanosti

and runaway skepticism and lack of transparency,

i porasta skepticizma i nedostatka transparetnosti,

or even just interestingness.

ili čak zainteresovanosti.

I mean, I find information just too interesting.

Hoću da kažem, za mene su informacije isuviše zanimljive.

It has a magnetic quality that draws me in.

Poseduju prvilačnost kojoj lako podležem.

So, visualizing information

Vizualizacija informacija

can give us a very quick solution to those kinds of problems.

nam daje veoma brzo rešenje ovakvih problema.

Even when the information is terrible,

A i onda kada su informacije užasne,

the visual can be quite beautiful.

njihova vizuelna komponenta može biti veoma lepa.

Often we can get clarity

I često nešto možemo razjasniti

or the answer to a simple question very quickly,

nešto ili pronaći odgovore na pitanja veoma brzo,

like this one,

kao što je ovo,

the recent Icelandic volcano.

nedavna erupcija vulkana na Islandu.

Which was emitting the most CO2?

Šta ispušta najviše ugljen dioksida?

Was it the planes or the volcano,

Da li su to avioni ili vulkan,

the grounded planes or the volcano?

prizemljeni avioni ili vulkani?

So we can have a look.

Pogledaćemo.

We look at the data and we see:

Gledamo podatke i vidimo

Yep, the volcano emitted 150,000 tons;

jeste, vulkan je ispustio 150000 tona;

the grounded planes would have emitted

prizemljeni avioni bi ispustili

345,000 if they were in the sky.

345000 da su bili u vazduhu.

So essentially, we had our first carbon-neutral volcano.

Pa tako, zapravo, ovo je prvi vulkan sa neutralnom emisijom ugljenika.

(Laughter)

(Smeh)

(Applause)

(Aplauz)

And that is beautiful. Thank you.

I to je ono što je lepo. Hvala vam.
