But Can You Do the Gerrymander?

It’s Friday. And that means you will likely be contorting on the dance floor this weekend. But if you tried to bend to conform to any of these congressional districts, you would likely break your back. Gerrymandering is an old practice that basically allows state governments to decide what area (and therefore populations) belong to which congressional district. If you carve up your opposition well enough, you can consolidate them into far fewer districts than they might otherwise win. Pennsylvania is just one such example of an unbalanced state. This interactive infographic game from Slate forces you to solve the jigsaw puzzle of congressional districts.

Women Bankers

…and not just any bankers but central bankers (the ones who establish policies at a national level), are rather under represented as this graphic from the Economist details. It is a nice use of small multiples with bar charts over time. Each bar is a 0–50% of the total membership of a central bank board and the share that is dark represents the number of women. Clearly for the countries selected not a single one has had a board of more than 50% women. Sweden and South Africa are the only two countries shown that have had 50% participation from women central bankers—though Norway and Denmark (for a period of time) have been consistently close.

Riding the Rails

A little while ago the Washington Post published this graphic on Metro ridership. But not just anybody’s ridership, that of the individuals who sit on the DC transit agency’s board. After all, should not those overseeing Washington’s transit agency be intimately familiar with the conditions faced by DC commuters?

The graphic is a really nice use of small multiples and shading and tinting to indicate which lines are travelled by specific persons. An icon of a bus denotes bus ridership. This is a very good piece.

Whip Counts to Authorise Force in Syria

I was catching up on some news tonight and I came upon an unhelpful graphic that was supposed to be helping me understand the whip count (who is voting yes or no) for authorising the use of force in Syria. Below is the original graphic from Think Progress.

The whip count as of 15.30 on 3 September

I struggled, however, to directly compare the yes and no votes. While I certainly understand that the splits within both parties are a fascinating subplot to the greater issue of will we bomb Syria, the traditional congressional arc visualisation is not helpful here. So using the same numbers, I simply plotted what is essentially a stacked bar chart. In truly heretical, i.e. independent, fashion I mixed the two parties together and placed them at either ends of the chart. The first to reach 50% wins. (If I were updating this live of course.)

Ye Olde Boston Mayoral Candidate Map

A map? Again? I know. But trust me, this one is interesting. For those of you who do not know, Boston’s Thomas Menino is not running for reelection this year. By the time he leaves office, he will have been the mayor of Boston for over twenty years and so this year is the first open election in a long, long time.

So what’s better than graphics for election-related data? Graphics with a medieval/Renaissance/fiefdom aesthetic, that’s what. With a little bit of fun, the Boston Globe mapped out the local areas of strength for the 12 candidates for mayor. The residence of each is denoted by a castle keep while areas of strength, location of donors, and key voting areas are signified in different colours. And the map’s background? Well, you can see for yourself.

Elections in Mali

For those of you who did not know, the country of Mali held elections yesterday and results should be forthcoming. Those of you who regularly read or semi-frequently check my blog, you are likely familiar with the work I did covering the French-led intervention in Mali. I am a bit busy working on some other projects, so I did not have the time to prepare a graphic for the election as I had hoped. Nor did many others. Alas, the only graphic I have come upon is from Al Jazeera. And it is a mess.

That map only shows the provinces; the colours signify nothing. Nor is there any context for the factettes on the side. And while perhaps the intention was to show Mali in a snapshot, I think a piece about the challenges facing Mali could delve a bit into forecasted statistics. I credit the team behind the project with attempting to cover the story, but aside from biographies on the four leading candidates and overviews of the main militant groups, the piece lacks depth and substance.

Ultimately, after looking at the work, I am left wanting more. A lot more.

Senate Facebook

Partisanship in Washington has only grown worse over time. So how better to track that than through Facebook-like network analysis diagrams?

If you look at senators who voted with other senators at least 50% of the time and at least 75% of the time, and compare those numbers to numbers over a decade ago, you can see there is a lot less bipartisanship in 2013.

Compare 2013…

to 2001.

Corporate Taxes

Corporate taxes are always a fun discussion point. Who pays too much? Too little? Not at all? In May, the New York Times published an interactive piece examining US companies and their effective tax rates from 2007 through 2012.

At its core, the piece is a bubble chart along one axis that plots the tax rate for the company, with the bubble sized proportionally to said company’s market capitalisation. Colours reinforce the tax rate plotting, but are not themselves necessary. I think they would have been better tied to something along the lines of industries or profit or sales growth.

Of course that was when I saw the button for viewing the data by industry. The view of all companies is broken up into a series of charts about each particular industry. And of course, if you want information on a particular company, the smart search/filter is particularly useful.

Extraditing Snowden

Edward Snowden is still on the run; he is still in the transit area of Moscow’s Sheremetyevo Airport without a passport to enter Russia. But if ever succeeds in extricating himself from his current predicament, Snowden presumably will seek to land in a country without an extradition treaty with the United States.

So in this interactive piece, the Guardian explores which countries have such treaties. The list serves as an index to the actual treaty texts. Beneath the globe are samples of different texts that show how an extradition treaty is drafted. The last piece highlights three countries that are possible options, but also options that have extradition treaties in place.

Federal Reserve Actions

Line charts can be a great way of looking at the impact of event over a metric over a set period of time. But what happens when you want to look at multiple metrics over that same period of time?

In this example from the New York Times, we have a series of line charts examining the impact of Federal Reserve actions over several years. Instead of attempting to conflate and confuse the issue by combining multiple charts into one, the designers chose to construct a vertical-running story that is linked by running narration. The final piece looks at four metrics: Federal Reserve assets, the S&P 500 index, the unemployment rate, and the labour force participation rate.

The use of the coloured bars in particular works to create and enforce the vertical narrative. The colour consistency across the four charts also aids in that effort. While an option like four small charts could have worked in one visual screen space, you would likely lose much of the detail and fidelity in the lines.
