National Geographic has a look at where and how we live:

The map shows population density; the brightest points are the highest densities. Each country is colored according to its average annual gross national income per capita, using categories established by the World Bank (see key below). Some nations — like economic powerhouses China and India — have an especially wide range of incomes. But as the two most populous countries, both are lower middle class when income is averaged per capita.

It’s interesting, but the map is a little wonky, because the income levels and population densities differ in granularity. It kind of works. Kinda doesn’t. There seems to be a lot of missing data — or does population density in northern Africa really drop off that quickly (it is desert land, albeit)? A little more explanation in the description or the legend would have been useful.

A few months ago, a packed crowd gathered in Minneapolis for the Eyeo Festival to hear some of the best in data art, visualization, and creative code talk about what they do and how they do it. I didn’t get a chance to go, but from all the chatter online during the event (and the stellar speaker lineup), I get the sense I missed something good. Luckily, some of the talks are available online.

For starters, Ben Fry and Casey Reas talk about Processing, their grad school grown programming language; Aaron Koblin presents some of the work from the Google Data Arts team; and Nicholas Felton discusses the process behind his annual reports.

Catch a few more on the Eyeo Vimeo channel or to stay updated for when new videos are uploaded.

This is totally sunshine and lollipops, but it has a good flow to it, and well, I totally wanted to know more about BBC Knowledge. Too bad it’s not available in my region that is America.

We do not provide these tables in Excel or CSV format. You will have to cut and paste from the pdf.

— A government group that provides a lot of data

If you’re going to provide a dataset to the public, or anyone for that matter, please don’t use PDF as your one and only format. At the very least, provide it in Excel. You can easily export spreadsheets to PDF. I don’t hold anything against the person who sent me this message. She was just doing her job. But organizations need to get with the times and provide data in a way that is actually usable.

In a follow-up to his ever popular McMap that showed distance to the nearest McDonald’s in the United States, Stephen Von Worley does the same for the United Kingdom and Ireland.

Not many people ride the train anymore, but a lot of inventory is still moved via freight. It turns out that 90 percent of that freight market belongs to just four companies in the country, and since deregulation in the 1980s, the number of total railroads has gone down from 50 to just 7. Nicolas Rapp, graphics director at Fortune Magazine, explains. The railroad coverage maps are interesting, too.

This Sunday will be 10 years since the attacks on September 11. Amanda Cox and Shan Carter of The New York Times look at the financial tally, an estimated $3.3 trillion:

Al Qaeda spent roughly half a million dollars to destroy the World Trade Center and cripple the Pentagon. What has been the cost to the United States? In a survey of estimates by The New York Times, the answer is $3.3 trillion, or about $7 million for every dollar Al Qaeda spent planning and executing the attacks. While not all of the costs have been borne by the government — and some are still to come — this total equals one-fifth of the current national debt. All figures are shown in today’s dollars.

A single cube in each stack represents $1 billion. The initial view is money spent in five categories. Click on any stack for a subcategory breakdown. Sobering.

In college, I was one of those guys who sat in the back and doodled in my notebook. Sometimes I fell asleep. One time I fell asleep and woke up in the middle of a different class. I blame the professor. Why would you turn off the lights for a two-hour session in a big lecture hall, while reading verbatim from world’s most boring powerpoint presentation?

Anyways, we all have our seating pockets that we like to settle in. Skyrill, a two-brother design team, took it upon themselves to visualize the seating habits of their graduate student classmates in class 15.514 at MIT.

Kiva, the microfinance site, lets you give small loans to people around the world to help them get their small business up and running. This animated map shows how 620,000 funded 615,000 borrowers, from the start of Kiva in 2005 up until now. Watch in full-screen for maximum effect.

Colors indicate loan type, which confused me at first, because I thought the map was saying that specific loan types were only given out during each time of year. It’s actually cycling through the loan types though, so you can see the breakdowns as the animation plays through, and then it shows all loans at once at the end of each year.

The only thing that’s missing are some counters for the amount of money passing hands. It’s been an impressive $240 million in loans around the world with a repayment rate of almost 99 percent.

In celebration of Chrome’s third birthday, Google teamed up with Hyperakt and Vizzuality to explore the evolution of the Web:

Over time web technologies have evolved to give web developers the ability to create new generations of useful and immersive web experiences. Today’s web is a result of the ongoing efforts of an open web community that helps define these web technologies, like HTML5, CSS3 and WebGL and ensure that they’re supported in all web browsers.

The black timelines show major browser releases. As you click each browser icon, you can see how the browser window has changed for each release, which I think is the most interesting part of the interactive.

Color bands represent browser technologies such as JavaScript, HTML, and Flash, and the bands grow as new browsers integrate the technologies. The intertwining of bands is supposed to show the interaction between different technologies, but it gets fuzzy here. Does the vertical position of bands mean anything? Does shape mean anything, or is it more for show? I think it’s a little of both. More the latter. Fun to poke around memory lane either way.

Slate places cartoon characters from past and present within the frame of a color wheel.

Why are the Smurfs blue? Why is Doug’s Beebe Bluff purple? Our aim is not to answer these existential questions. When asked why the Simpsons are yellow, Yeardley Smith (voice of Lisa) explained only that Matt Groening “thought that it would be really funny if, when people watched The Simpsons, they thought that maybe the color on their TV was off.”

Totally ridiculous. And that’s what makes it fun.

[Thanks, Dean]

Most of us have gone through the paces of algebra through calculus in high school. I remember lots of problems and fact sheets. Sol Garfunkel and David Mumford imagine a math education system that teaches skills for the real world and increases quantitative literacy:

Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering. In the finance course, students would learn the exponential function, use formulas in spreadsheets and study the budgets of people, companies and governments. In the data course, students would gather their own data sets and learn how, in fields as diverse as sports and medicine, larger samples give better estimates of averages. In the basic engineering course, students would learn the workings of engines, sound waves, TV signals and computers. Science and math were originally discovered together, and they are best learned together now.
