Happy Friday, everyone. Foul balls are the souvenirs of fortune at baseball games. (Home runs as well I suppose.) You can’t buy them, you can only hope to be one of the lucky few who catch one. So the Boston Globe ran an article with an integrated interactive piece that told the story of a select few foul balls caught by fans at ten games at Fenway. But from the data visualisation side, they plotted where each foul ball landed. But, the real gem is that they then had a few small multiples showing where various Boston hitters tended to deposit their fouls.

I just finished reading Tacitus’ account of his father-in-law Agricola. Agricola is the Roman—more likely from a family of Romanised Gauls—general who conquered Great Britain for Rome. His crowning victory was the Battle of Mons Graupius. It should all be taken with a grain of salt, because there are no other corroborating sources—to my knowledge. For one thing, nobody knows for sure where this battle occurred—if it did—other than somewhere in what is now Scotland. So, I decided to attempt to illustrate the battle as I couldn’t find a satisfactory one on the internets. Again, with the knowledge that Tacitus’ account is not the most thorough.
Baltimore is going crazy, if you haven’t heard. So the LA Times put together a set of maps putting the riots in context. They look at the racial makeups of the neighbourhoods with the violence along with median income and education.

Today the Supreme Court takes up gay marriage. Again. This is, you know, after they decided two years ago that the federal government has to recognise gay marriages when performed in states where it is legal. Anyway, last week, Bloomberg Business looked at the United States preference for changing its mind through a nice series of charts.
How interracial marriage changed in the US
They took six key issues, including interracial marriage shown above, and looked at how the position shifted over time. They identified the basic trend as being early adopter states followed by rapid acceptance to a critical mass, at which time the federal government stepped in, e.g. via the Supreme Court.

It is finally Friday. And if you are in one of those areas where it is forecast to rain this weekend, you may find yourself watching a film. If you do, then xkcd has a post that will help you identify the movie by its background scenery.
Where in the United States is your film’s protagonist?
Personally, my favourite is the reference to the Grand Banks in Hunt for Red October.
Today’s piece comes via my co-worker and is about the growth of urban Walmart stores. The article is from NPR and includes a nice series of small multiples of store locations in three select cities: Washington, Chicago, and Atlanta. In full disclosure, I live about two blocks from one of the urban Walmarts in Chicago. So go figure.

Your humble author is still on holiday. So, today, you can enjoy a nice interactive piece from FiveThirtyEight that predicts the results of the 7 May general election. Of particular interest, the box part of the plot that shows the 90% confidence range.
Dot plotting the results
The piece also has a choropleth map. My only feature request(s) would be to have a zoom feature for urban constituencies and/or to have a search field that allows the user to see the predicted results for a specific constituency.

North Dakota’s economy has been booming because of shale oil. Most of that economic growth has been centred on what was the small city of Williston, North Dakota. Economic growth often leads to population growth, however, and that can at times lead to growth in less than wholesome economic activities. The National Journal took a look at the population growth in the area and what has been happening concurrently in a few metrics of the less wholesome sectors of the economy, i.e. drugs and prostitution. Turns out, they are both up.

Spring has finally arrived. And that means that far to your humble author’s north, the sea ice in the Arctic is beginning to recede from its annual maximum coverage. However, this year’s coverage was the smallest since satellite records began in 1979. The New York Times covers the story in a nice article with two big data pieces. The first is a really nice map—not shown—that looks at this year’s coverage compared to average extents.
The really nice part, however, is a line chart of historical ice coverage from 1979 through to the current date. While the piece is not interactive, the annotations in the graphic do a nice job explaining the different lines and outliers. Overall, a solid piece.
