  • It feels like we're all suffering

  • from information overload or data glut.

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

  • and that's using our eyes more.

  • So, visualizing information, so that we can see

  • the patterns and connections that matter

  • and then designing that information so it makes more sense,

  • or it tells a story,

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

  • Failing that, visualized information can just look really cool.

  • So, let's see.

  • This is the $Billion Dollar o-Gram,

  • and this image arose

  • out of frustration I had

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

  • That is, they're meaningless without context:

  • 500 billion for this pipeline,

  • 20 billion for this war.

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

  • is visually and relatively.

  • So I scraped a load of reported figures

  • from various news outlets

  • and then scaled the boxes according to those amounts.

  • And the colors here represent the motivation behind the money.

  • So purple is "fighting,"

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

  • And what you can see straight away

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

  • You can literally see them.

  • But more importantly, you start to see

  • patterns and connections between numbers

  • that would otherwise be scattered across multiple news reports.

  • Let me point out some that I really like.

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

  • 780 billion a year.

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

  • that's their climate change fund.

  • Americans, incredibly generous people --

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

  • compared with the amount of foreign aid

  • given by the top 17 industrialized nations

  • at 120 billion.

  • Then of course,

  • the Iraq War, predicted to cost just 60 billion

  • back in 2003.

  • And it mushroomed slightly. Afghanistan and Iraq mushroomed now

  • to 3,000 billion.

  • So now it's great

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

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

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

  • by the debt that Africa owes to the West?

  • Let's take a look.

  • So there it is:

  • 227 billion is what Africa owes.

  • And the recent financial crisis,

  • how much of this diagram might that figure take up?

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

  • Dooosh -- Which I think is the appropriate sound effect

  • for that much money:

  • 11,900 billion.

  • So, by visualizing this information,

  • we turned it into a landscape

  • that you can explore with your eyes,

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

  • And when you're lost in information,

  • an information map is kind of useful.

  • So I want to show you another landscape now.

  • We need to imagine what a landscape

  • of the world's fears might look like.

  • Let's take a look.

  • This is Mountains Out of Molehills,

  • a timeline of global media panic.

  • (Laughter)

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

  • But the height here, I want to point out,

  • is the intensity of certain fears

  • as reported in the media.

  • Let me point them out.

  • So this, swine flu -- pink.

  • Bird flu.

  • SARS -- brownish here. Remember that one?

  • The millennium bug,

  • terrible disaster.

  • These little green peaks

  • are asteroid collisions.

  • (Laughter)

  • And in summer, here, killer wasps.

  • (Laughter)

  • So these are what our fears look like

  • over time in our media.

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

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

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

  • that you can only see when you visualize it.

  • Let me highlight it for you.

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

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

  • twin peaks every year.

  • If we look closer, we see those peaks occur

  • at the same month every year.

  • Why?

  • Well, November, Christmas video games come out,

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

  • But April isn't a particularly massive month

  • for video games.

  • Why April?

  • Well, in April 1999 was the Columbine shooting,

  • and since then, that fear

  • has been remembered by the media

  • and echoes through the group mind gradually through the year.

  • You have retrospectives, anniversaries,

  • court cases, even copy-cat shootings,

  • all pushing that fear into the agenda.

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

  • See that gap there? There's a gap,

  • and it affects all the other stories.

  • Why is there a gap there?

  • You see where it starts? September 2001,

  • when we had something very real

  • to be scared about.

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

  • and I keep hearing a phrase

  • all the time, which is this:

  • "Data is the new oil."

  • Data is the kind of ubiquitous resource

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

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

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

  • especially if you live around the Gulf of Mexico,

  • but I would, perhaps, adapt this metaphor slightly,

  • and I would say that data is the new soil.

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

  • Over the years, online,

  • we've laid down

  • a huge amount of information and data,

  • and we irrigate it with networks and connectivity,

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

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

  • But it's a really fertile medium,

  • and it feels like visualizations, infographics, data visualizations,

  • they feel like flowers blooming from this medium.

  • But if you look at it directly,

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

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

  • interesting things can appear and different patterns can be revealed.

  • Let me show you this.

  • Can you guess what this data set is?

  • What rises twice a year,

  • once in Easter

  • and then two weeks before Christmas,

  • has a mini peak every Monday,

  • and then flattens out over the summer?

  • I'll take answers.

  • (Audience: Chocolate.) David McCandless: Chocolate.

  • You might want to get some chocolate in.

  • Any other guesses?

  • (Audience: Shopping.) DM: Shopping.

  • Yeah, retail therapy might help.

  • (Audience: Sick leave.)

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

  • Shall we see?

  • (Laughter)

  • (Applause)

  • So, the information guru Lee Byron and myself,

  • we scraped 10,000 status Facebook updates

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

  • and this is the pattern we found --

  • people clearing out for Spring Break,

  • (Laughter)

  • coming out of very bad weekends on a Monday,

  • being single over the summer,

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

  • Who would do that?

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

  • unprecedented.

  • But if you ask the right kind of question,

  • or you work it in the right kind of way,

  • interesting things can emerge.

  • So information is beautiful. Data is beautiful.

  • I wonder if I could make my life beautiful.

  • And here's my visual C.V.

  • I'm not quite sure I've succeeded.

  • Pretty blocky, the colors aren't that great.

  • But I wanted to convey something to you.

  • I started as a programmer,

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

  • in print, online and then in advertising,

  • and only recently have I started designing.

  • And I've never been to design school.

  • I've never studied art or anything.

  • I just kind of learned through doing.

  • And when I started designing,

  • I discovered an odd thing about myself.

  • I already knew how to design,

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

  • but more like I was sensitive

  • to the ideas of grids and space

  • and alignment and typography.

  • It's almost like being exposed

  • to all this media over the years

  • had instilled a kind of dormant design literacy in me.

  • And I don't feel like I'm unique.

  • I feel that everyday, all of us now

  • are being blasted by information design.

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

  • and we're all visualizers now;

  • we're all demanding a visual aspect

  • to our information.

  • There's something almost quite magical about visual information.

  • It's effortless, it literally pours in.

  • And if you're navigating a dense information jungle,

  • coming across a beautiful graphic

  • or a lovely data visualization,

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

  • I was curious about this, so it led me

  • to the work of a Danish physicist

  • called Tor Norretranders,

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

  • So here we go. This is your senses,

  • pouring into your senses every second.

  • Your sense of sight is the fastest.

  • It has the same bandwidth as a computer network.

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

  • And then you have hearing and smell,

  • which has the throughput of a hard disk.

  • And then you have poor old taste,

  • which is like barely the throughput of a pocket calculator.

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

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

  • So a lot of your vision --

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

  • It's unconscious.

  • The eye is exquisitely sensitive

  • to patterns in variations in color, shape and pattern.

  • It loves them, and it calls them beautiful.

  • It's the language of the eye.

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

  • which is about words and numbers and concepts,

  • you start speaking two languages simultaneously,

  • each enhancing the other.

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

  • And that whole thing -- it's two languages

  • both working at the same time.

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

  • to alter our perspective or change our views.

  • Let me ask you a simple question

  • with a really simple answer:

  • Who has the biggest military budget?

  • It's got to be America, right?

  • Massive. 609 billion in 2008 --

  • 607, rather.

  • So massive, in fact, that it can contain

  • all the other military budgets in the world inside itself.

  • Gobble, gobble, gobble, gobble, gobble.

  • Now, you can see Africa's total debt there

  • and the U.K. budget deficit for reference.

  • So that might well chime

  • with your view that America

  • is a sort of warmongering military machine,

  • out to overpower the world

  • with its huge industrial-military complex.

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

  • Because America is an incredibly rich country.

  • In fact, it's so massively rich

  • that it can contain the four other

  • top industrialized nations' economies

  • inside itself, it's so vastly rich.

  • So its military budget is bound to be enormous.

  • So, to be fair and to alter our perspective,

  • we have to bring in another data set,

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

  • Who has the biggest budget as a proportion of GDP?

  • Let's have a look.

  • That changes the picture considerably.

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

  • and American drops into eighth.

  • Now you can also do this with soldiers.

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

  • Of course, 2.1 million.

  • Again, chiming with your view

  • that China has a militarized regime

  • ready to, you know, mobilize its enormous forces.

  • But of course, China has an enormous population.

  • So if we do the same,

  • we see a radically different picture.

  • China drops to 124th.

  • It actually has a tiny army

  • when you take other data into consideration.

  • So, absolute figures, like the military budget,

  • in a connected world,

  • don't give you the whole picture.

  • They're not as true as they could be.

  • We need relative figures that are connected to other data

  • so that we can see a fuller picture,

  • and then that can lead to us changing our perspective.

  • As Hans Rosling, the master,

  • my master, said,

  • "Let the dataset change your mindset."

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

  • Take a look at this one.

  • I'm a bit of a health nut.

  • I love taking supplements and being fit,

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

  • There's always conflicting evidence.

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

  • This is a visualization of all the evidence

  • for nutritional supplements.

  • This kind of diagram is called a balloon race.

  • So the higher up the image,

  • the more evidence there is for each supplement.

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

  • So you can immediately apprehend

  • the relationship between efficacy and popularity,

  • but you can also, if you grade the evidence,

  • do a "worth it" line.

  • So supplements above this line are worth investigating,

  • but only for the conditions listed below,

  • and then the supplements below the line

  • are perhaps not worth investigating.

  • Now this image constitutes a huge amount of work.

  • We scraped like 1,000 studies from PubMed,

  • the biomedical database,

  • and we compiled them and graded them all.

  • And it was incredibly frustrating for me

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

  • and I spent a month doing this,

  • and I only filled two pages.

  • But what it points to

  • is that visualizing information like this

  • is a form of knowledge compression.

  • It's a way of squeezing an enormous amount

  • of information and understanding

  • into a small space.

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

  • and once it's there,

  • you can do cool stuff like this.

  • So I converted this into an interactive app,

  • so I can now generate this application online --

  • this is the visualization online --

  • and I can say, "Yeah, brilliant."

  • So it spawns itself.

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

  • that affects heart health."

  • So let's filter that out.

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

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

  • I just want to see plants and --

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

  • Now this app is spawning itself

  • from the data.

  • The data is all stored in a Google Doc,

  • and it's literally generating itself from that data.

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

  • and I can update it in a second.

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

  • Doosh! Again, the image recreates itself.

  • So it's cool.

  • It's kind of living.

  • But it can go beyond data,

  • and it can go beyond numbers.

  • I like to apply information visualization

  • to ideas and concepts.

  • This is a visualization

  • of the political spectrum,

  • an attempt for me to try

  • and understand how it works

  • and how the ideas percolate down

  • from government into society and culture,

  • into families, into individuals, into their beliefs

  • and back around again in a cycle.

  • What I love about this image

  • is it's made up of concepts,

  • it explores our worldviews

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

  • to see what others think,

  • to see where they're coming from.

  • And it feels just incredibly cool to do that.

  • What was most exciting for me

  • designing this

  • was that, when I was designing this image,

  • I desperately wanted this side, the left side,

  • to be better than the right side --

  • being a journalist, a Left-leaning person --

  • but I couldn't, because I would have created

  • a lopsided, biased diagram.

  • So, in order to really create a full image,

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

  • and at the same time, uncomfortably recognize

  • how many of those qualities were actually in me,

  • which was very, very annoying and uncomfortable.

  • (Laughter)

  • But not too uncomfortable,

  • because there's something unthreatening

  • about seeing a political perspective,

  • versus being told or forced to listen to one.

  • You're capable of holding conflicting viewpoints

  • joyously when you can see them.

  • It's even fun to engage with them

  • because it's visual.

  • So that's what's exciting to me,

  • seeing how data can change my perspective

  • and change my mind midstream --

  • beautiful, lovely data.

  • So, just to wrap up,

  • I wanted to say

  • that it feels to me that design is about solving problems

  • and providing elegant solutions,

  • and information design is about

  • solving information problems.

  • It feels like we have a lot of information problems

  • in our society at the moment,

  • from the overload and the saturation

  • to the breakdown of trust and reliability

  • and runaway skepticism and lack of transparency,

  • or even just interestingness.

  • I mean, I find information just too interesting.

  • It has a magnetic quality that draws me in.

  • So, visualizing information

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

  • Even when the information is terrible,

  • the visual can be quite beautiful.

  • Often we can get clarity

  • or the answer to a simple question very quickly,

  • like this one,

  • the recent Icelandic volcano.

  • Which was emitting the most CO2?

  • Was it the planes or the volcano,

  • the grounded planes or the volcano?

  • So we can have a look.

  • We look at the data and we see:

  • Yep, the volcano emitted 150,000 tons;

  • the grounded planes would have emitted

  • 345,000 if they were in the sky.

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

  • (Laughter)

  • (Applause)

  • And that is beautiful. Thank you.

  • (Applause)

It feels like we're all suffering
