Fresh Water Bulge in the Arctic Ocean

The BBC has an article on a discovery of a growing bulge of fresh water in the Arctic Ocean. The top of the article includes a large set of graphics that explains the story below and links to an animation. The animation depicts the growth of the Arctic ice sheet from the pressure beneath and plots the height of the ice.

How the Costa Concordia Sank

The Costa Concordia sank nearly a week ago, but the questions of exactly how and why she sank will likely linger for much longer.

The BBC has had extensive coverage of the story, including this page that details what is known about how and why the cruise ship sank.

School’s Out For Ever

While on holiday, the Archdiocese of Philadelphia announced a sweeping series of school closures and consolidations in an effort to create a smaller and more sustainable school system. As I spent my earlier years of education in the parochial system I had more than a passing interest in the story.

The Philadelphia Inquirer mapped out the changes, a cropping of which is below. As one can easily see, the bulk of the cuts came in the city itself and the suburbs in Montgomery County. The more distant, read wealthier, suburbs fared much better. Chester County, for example had a total of only two closings. Bucks only five.

12 Days of Christmas (Corporate-ified)

Guess what? It’s Christmas season.

I am taking two weeks holiday starting tomorrow and so posting here shall be rather light until early January.

In business world, people like PowerPoint presentations with charts that show the flow of synergy. Scales of efficiency. Action item prioritisation. The kinds of things that the rest of us don’t every really need or want to understand. But, at happyplace.com, they have posted a series of Christmas charts and graphs that would feel right at home in such a presentation. Below is a flowchart showing the progression of the 12 Days of Corporate Christmas.

Earth-sized Planets

Kepler 20 System
Kepler 20 System

We have finally discovered two planets outside our solar system that have roughly the same size as Earth. Unfortunately, unless we learn that life can exist in the form of fire beings, these two planets are too close to their sun to support life. Their temperatures are in the hundreds and thousands of degrees. A bit balmy.

The New York Times has a small but interesting chart that fits inline with its article, at least on its website—presumably it fits similarly in its printed form. Seen here to the left, it plots the orbital distance of the planets that are known to orbit the star Kepler 20. (Unfortunately these planets have less than creative names: Kepler 20e and Kepler 20f.) The other planets are gas giants.

The use of scale of orbits and the gap between 20f and 20d allow for an annotation within the image. And then with a little bit more vertical space, to drive hom the point of these new planets’ nearness to their sun, the orbit of Mercury, the planet nearest our sun, is plotted for comparison.

The Family Tree of Kim Jong Il

Kim Jong Il is dead. And nobody really knows what is going to happen in North Korea.

But, what we do have, is the interactive family tree of Kim Jong Il, courtesy of the BBC. Select individuals are clickable and have short biographical sketches. Unfortunately, the tree has been simplified for clarity and it does not contain all members of the family.

The Rise of Newt

The Iowa caucuses are quickly approaching. And that means for many candidates a scramble to gain as many supporters as possible and then convert their poll ratings into votes. For the Republicans, this has been a truly topsy-turvy cycle with the distant refrain of “anyone but Mitt” echoing in the background.

So, here we are looking at the return of Newt Gingrich. Over the weekend, the New York Times published a graphic comprised of small multiples of poll numbers for the various candidates. Each chart plots the individual polls and then the moving average.

What one can clearly see is a moving wave of discontent. It begins small with Michelle Bachmann before rising with the arrival of Rick Perry. He floundered, however, and was soon overtaken by Herman Cain. And as his support ebbed, it buoyed Gingrich to the top or near-top, depending on the poll, of the Republican candidates.

All in all, a good series of charts that tells a convincing story rather quickly and succinctly.

The Finances of Social Security

Simple graphs can tell great stories with little annotations. This graphic by the New York Times illustrates that point well with a stacked line chart set behind a line on the same scale. The two should match, or at least the red should be beneath the greys. When they don’t, you have a story and the Times calls it out.

Killed in Action in Iraq, State by State

The Iraq War is over. And now it is time to reflect on what we have gained and what we have lost. This map by the Guardian details the number of soldiers killed in action in Iraq. (Other options include total wounded, killed by non-hostile, &c.)

Unfortunately, I call it a ‘no kidding’ type of map. The data, accessible via the Guardian here, corresponds nicely with a list of states by total population. Of the top ten countries in KIA, only Virginia is not among the top ten in population; it is 12th. The country thus not in the top ten in KIA, but in population is North Carolina. It’s rank in terms of KIA? 11th.

The data is interesting and worth depicting if we are to reflect. But, perhaps a more suitable visualisation could have been chosen.

On a personal note, these Google Maps overlays are annoying when, in the cases of, e.g., Wisconsin and Massachusetts, the shapes are incorrect. Perhaps coastlines are not as easy as states with ‘straight lines’ for boders, but we would do well to try and make irregular coasts at least somewhat correct.
