This will be lost on many of you, but to the programmers this will make perfect sense. Basically, when programming, there are a lot of times when you have a long list of numbers or words that you’ll want sorted greatest to least or alphabetically. The way this is done will vary by what algorithm you use. Aldo Cortesi visualizes these sorting algorithms, showing just how each one works.

If you’re confused but still interested, here’s a simple example.

Let’s say you have a list of numbers from one to five listed as such: 4, 20, 6, 12, 100. We want to organize these systematically least to greatest. The easiest way would be to setup five “spots” and then go through each number, starting at the beginning, and decide if the number is bigger or smaller than the number we already looked at. That’s not the most efficient way to do it though, and when you have millions of numbers to sort, instead of just five, then efficiency matters.

From Ben Fry’s newly established Fathom Information Design, is a visualization for GE on our aging world:

According to the United Nations, the elderly population of the world is growing at its fastest rate ever. By 2050, there will be more than 2 billion people aged 60 or over. The age of a country’s population can reveal insights about that country’s history, and can provide a glimpse towards the economic and healthcare trends that will challenge their societies in the future.

The piece is a simple but elegant interactive that lets you compare age distributions between countries, over time. Select one country on the top, and select another on the bottom. For each country, you get a pair of stacked bars (for men and women). Age moves left to right, so the left-most bars represent the youngest, and the right most represent the oldest.

Use the slider on the bottom to navigate through time, and the distributions shift further right (i.e. people live longer) in a wave-like motion, as the population of each respective country increases.

Finally, watch a composite of all eight selected countries in the bottom right.

The one thing missing for me is the percentages for each age/gender group as you roll over each bar. But I’m just being picky. Really good stuff. The interactive leaves it up to you to see what’s going on in the data.

How does your country compare to others?

Sure, why not, let’s make it a hairy Friday. From Tor Weeks: a series of moustaches styled by their typographic counterpart, aka typestaches. The big and bold typefaces like Federal and Wide Latin get thick and burly moustaches, while the more delicate typefaces, get thin and curvy.

If only facial hair were as easy to select as fonts. I’d get myself a 24pt Mr. Century Ultra.

The Beatles were famously known for their mop-top haircuts in the early 1960s, but their styles evolved over time. DeviantArt user mozzarellapoppy has a look at the hair, moustache, and spectacle changes over an eight-year span. Watch as they slowly morph into The Bee Gees.

Yeah, you read that right. Tardiness makes the world go ’round:

One day in 1939, Berkeley doctoral candidate George Dantzig arrived late for a statistics class taught by Jerzy Neyman. He copied down the two problems on the blackboard and turned them in a few days later, apologizing for the delay — he’d found them unusually difficult. Distracted, Neyman told him to leave his homework on the desk.

On a Sunday morning six weeks later, Neyman banged on Dantzig’s door. The problems that Dantzig had assumed were homework were actually unproved statistical theorems that Neyman had been discussing with the class — and Dantzig had proved both of them. Both were eventually published, with Dantzig as coauthor.

Other benefits include more hours of sleep, exercise while power-walking to your destination, and all-around warm, fuzzy feelings knowing that you live by nobody’s schedule. You might also supposedly inspire films like Good Will Hunting.

NASA has mapped the world’s forest heights, based on satellite data, for a first-of-its-kind global view. While there are plenty of maps that show forest height regionally and locally, this is the first time it’s been mapped globally with a single, uniform method.

The new map shows the world’s tallest forests clustered in the Pacific Northwest of North America and portions of Southeast Asia, while shorter forests are found in broad swaths across northern Canada and Eurasia. The map depicts average height over 5 square kilometers (1.9 square miles) regions), not the maximum heights that any one tree or small patch of trees might attain.

These heights range from 0 to 70 meters. The darker the green the higher the tree canopies.

NASA believes the new map could help scientists with a new perspective on how much carbon forests store and more insight on carbon cycles within ecosystems.

In response to the the 9/11 attacks, the United States government created a highly secretive set of organizations with zero transparency and very little oversight. How much money do these secret programs cost? How many people do they employ? The Washington Post reports on Top Secret America:

These are some of the findings of a two-year investigation by The Washington Post that discovered what amounts to an alternative geography of the United States, a Top Secret America hidden from public view and lacking in thorough oversight. After nine years of unprecedented spending and growth, the result is that the system put in place to keep the United States safe is so massive that its effectiveness is impossible to determine.

The series of articles, video, and graphics, allow readers to explore the information themselves.

Of main interest: a network diagram shows organizations and their top secret activities and a map shows the geographic distribution of government organizations and companies within Top Secret America.

Click on a specific organization for within group breakdowns. At this point it gets a little confusing with drill-down pie charts, especially if you’re just browsing, and a spiral view is also offerred which feels extraneous. The overall story and heavy research, however, makes it worth clicking through the clunky at times set of interactives.

In the same spirit of the original coffee drink infographic from a few years ago, Plaid Creative describes the perfect pour, or as I like to call it, the citizen’s guide to fancy pants coffee drinks. At its root, its a series of pie charts where each wedge represents the percentage of ingredient in a given fancy pants drink. But the subtle stylings make it look so much more delicious, from the pattern fills out to the mug-like border.

Peter Barber, head of Map Collections at the British Library reports for the The Daily Mail ten of the greatest maps that changed the world. The number one listed (above) is Be On Guard! from 1921:

The infant USSR was threatened with invasion, famine and social unrest. To counter this, brilliant designers such as Dimitri Moor were employed to create pro-Bolshevik propaganda.

Using a map of European Russia and its neighbours, Moor’s image of a heroic Bolshevik guard defeating the invading ‘Whites’ helped define the Soviet Union in the Russian popular imagination.

Others include Google Earth, Charles Booth’s map of London poverty, and the earliest known Chinese terrestrial globe from 1623.

Tim O’Reilly and Aneesh Chopra, Federal Chief Technology Officer sit down for a chat on the US government’s goals on open data and information accessibility. Disregard the infomercial feel to it. There’s some interesting tidbits in there, albeit pretty broad.

Uses for data

Chopra brings up two examples on how the government is getting involved, and what’s interesting about them is that it’s not what most have in mind. It’s not about money matters or policy-making.

You’ve seen the presentation. You’ve seen the motion graph tool. But up until now, the data exploration tool, Trendalyzer, has always been in the browser. Now you can download the desktop version, and keep everything on your own computer with Gapminder Desktop:

Gapminder Desktop is particularly useful for presentations as it allows you to prepare your graphs in advance and you won’t need an Internet connection at your lecture or presentation.

In the “list of graphs” you will get at preset list of graphs on the left side, but you can also very easily create your own favorite examples. Simply arrange the graph the way you want it and click “bookmark this graph”. Your example will the appear in your own list of favorite graphs. Perfect when you want to prepare a lecture or presentation.

Basically, it’s the exact same thing as the online version as an Adobe Air application, which is handy for all you motion graph fans out there.

Time Warner Cable explains how a picture travels from Jeff’s phone to Vijay’s laptop. Obviously it is a bit simplified. I spent a full semester on step four alone back in my electrical engineering days, and still don’t know what the heck happens there. That was a rough semester.

Technology and investment group HackFwd describes what it’s like to work with them in a flowchart. In a nutshell: start with inspiration, work hard, impress people, work hard, and reap the rewards. And then start all over again.

Augmented reality, a computer trick to place the virtual within the real world, has barely cracked its way into most of our lives, but it’s easy to see how such a tool could get out of hand. At some point, we’re going to have to raise our hands and say, “Okay, stop that’s enough information. My head hurts.” Or will we? Recent architecture grad Keiichi Matsuda explores the possibility of an augmented (hyper)reality where information is everywhere you go (video below). Read More

Prospect Magazine takes a look at how Britain has changed by the numbers from 1997 to present:

Richer, fatter, living longer, more indebted, drunker, better connected, politically disillusioned: there’s no metric that can describe whether we are happier or living better lives after 13 years of Labour. But there are plenty to show how we have changed during a period of fulsome spending, borrowing and technological transformation.

The four pages of graphics are well-organized with just the right balance of color and iconography, to keep the reader engaged without going oatmeal on the numbers.
