Today’s post clearly fits within the storyline of mapping, redistricting, and gerrymandering over the last week or so, but the work is a bit older. (Side note, the previously highlighted Pennsylvania 7th Congressional District, well it is in the news for a different story, its congressman just announced he would not be standing for reelection because of a sexual harassment case.)
We have the work of xkcd presenting the 2016 election results, but by mapping out the votes (approximately) in terms of 250,000 voters. It does a good job of showing you just where the population of the United States is concentrated (and vice versa).
The last two weeks we twice looked at gerrymandering as it in particular impacted Pennsylvania, notorious for its extreme gerrymandered districts. And now that the state will have to redraw districts to be less partisan, will Pennsylvania usher in a series of court orders from other state supreme courts, or even the federal Supreme Court, to create less partisan maps?
To that specific question, we do not know. But as we get ever closer to the 2020 Census that will lead to new maps in 2021, you can bet we will discuss gerrymandering as a country. Maybe to jumpstart that dialogue, we have a fantastic work by FiveThirtyEight, the Gerrymandering Project.
Since we focus on the data visualisation side of things, I want to draw your attention to the Atlas of Redistricting. This interactive piece features a map of House districts, by default the current map plan. The user can then toggle between different scenarios to see how those scenarios would adjust the Congressional map.
If, like me, you live in an area with lots of people in a small space, you might need to see Pennsylvania or New Jersey in detail. And by clicking on the state you can quickly see how the scenarios redraw districts and the probabilities of parties winning those seats. And at the bottom of the map is the set of all House seats colour-coded by the same chance of winning.
But what I really love about this piece is the separate article that goes into the different scenarios and walks the user through them, how they work, how they don’t work, and how difficult they would be to implement. It’s not exactly a quick read, but well worth it, especially with the map open in a separate tab/window.
Overall, a solid set of work from FiveThirtyEight diving deep into gerrymandering.

During my travels in Europe, I enjoyed very little sunshine. It did not rain often, but the skies were overcast in both Scandinavia and London. Turns out that at least in January, after my trip, Europe was covered in an inordinate amount of sunshine. The Guardian covered the story, with a graphic showing just how little sunshine has been seen in northern Europe.

Here in Pennsylvania this week, the state Supreme Court will hear arguments on the legality of congressional districts drawn by Republicans in 2010. The state is rather evenly split between Republicans and Democrats, e.g. Donald Trump won by less than one percentage point or less than 45,000 votes. But 13 of its 18 congressional districts are represented by Republicans, roughly 72%.
This graphic is from the New York Times Upshot and it opens a piece that explores gerrymandering in Pennsylvania. The graphic presents the map today as well as a nonpartisan map and an “extreme” gerrymander. The thing most noticeable to me was that even with the nonpartisan geography, the Democrats are still below what they might expect for a near 50-50 split. Why? One need only look at Philadelphia and Pittsburgh where, using the Times’ language, the Democrats “waste” votes with enormous margins, leaving the suburban and rural parts of the state open for Republican gains.

In the United Kingdom, the month of January has been less than stellar for the National Health Service, the NHS, as surgeries have been cancelled or delayed, patients left waiting in corridors, and a shortage of staff to cope with higher-than-usual demand.
But another problem is the shortage of hospital beds, which compounds problems elsewhere in hospitals and health services. The Guardian did a nice job last week of capturing the state of bed capacity in some hospitals. Overall, the piece uses line charts and scatter plots to tell the story, but this screenshot in particular is a lovely small multiples set that shows how even with surge capacity, the beds in orange, many hospitals are running at near 100% capacity.
The Winter Olympics are creeping ever closer and so this piece from the New York Times caught my eye. It examines the impact of climate change on host cities for the Winter Olympics. Startlingly, a handful of cities from the past almost century are no longer reliable enough, i.e. cold and snow-covered, to host winter games.
This screenshot is of a bar chart that looks at temperatures, because snow and ice obviously require freezing temperatures. The reliability is colour-coded and at first I was not a fan—it seemed unnecessary to me.
But then further down the piece, those same colours are used to reference reliability on a polar projection map.
That was a subtle, but well appreciated design choice. My initial aversion to the graphic and piece was changed by the end of it. That is always great when designers can pull that off.

January is the month of forecasts and projections for the year to come. And the Economist is no different. Late last week it published a datagraphic showcasing the GDP growth forecasts of the Economist Intelligence Unit. I used to make this exact type of datagraphic a lot. And I mean a lot. But what I really enjoy is how successfully this piece integrates the map, the bar chart, and the tables to round out the story.
The easy thing to do is always the map, because people like maps. They can be big, and if the data set is robust, full of data and colour. But maps hide and obscure geographically small countries. And then you have to assume that people know all the countries in the world. Problem is, most people do not.
So the bar chart does a good job of showing each country as equals, a slim vertical bar. In such a small space, labelling every country is impossible, but the designers chose a select number of countries that might be of interest and called them out across the entire series.
Lastly, people always like to know who is #winning and who is a #loser. So the tables at the extreme ends of the chart showcast the top and last five.
I may have rearranged some of the elements, and dropped the heavy black rules between the bins on the legend, but overall I consider this piece a success.

This past weekend I saw the film Darkest Hour with one of my mates. The film focuses on Winston Churchill at the very beginning of his term as prime minister. Coincidentally I was walking through some of the very rooms and corridors depicted in the film—and rather accurately I should say—just one week prior.
One of the things in the real place that caught my eye in particular was the Map Room Annex. Most people know about the Map Room proper, from which the British Empire’s war effort was coordinated, but the annex contained data on wartime casualties, material production, &c. Consequently the walls were lined with displays of that data. But this was also the early 1940s and so none of it was computerised. Instead, we had handmade charts.
Alas, the space is quite narrow and the museum was quite crowded. So I only managed a snapshot or two, but I think this one does some justice to the hardworking folks producing charts about the war.

This is a piece from a few years ago, but the New York Times cleverly brought it to the front of their Upshot page. And it seemed just so appropriate. Many of you are likely travelling today—I’m not, I’m headed to work—and many of you will be driving or taking the train. But some will be flying. But to and from where?
The map has some nice features that allow you to selectively few particular cities. Philadelphia has relatively few travellers by air, but that’s probably because places in the Northeast are more easily accessible by road or rail.
Chicago also has relatively few travellers, though more than Philadelphia. I would posit that is because most people are not flying to visit their relatives, but rather driving to places in Wisconsin, Iowa, and Indiana.
No post tomorrow, because I intend on sleeping in. But you can expect something on Friday.

I was reading the Sunday paper yesterday and whilst I normally skip the sports section, especially during baseball’s offseason, this time a brightly coloured map caught my attention. Of course then I had to read the article, but I am glad that I did.
On Sunday the New York Times ran a print piece—I mean I assume I can find it online (I did.)—about CBS chooses which American football matches to air in the country’s markets. It is a wee bit complicated. And if you can find it, you should read it. The process is fascinating.
But I want to quickly talk about the design of the thing. Remember how I said a map caught my attention. That was pretty important, because the map was not the largest part of the article. Instead that went to a nice big photo. But the information designer I am, well, my eyes went straight to the map below that.
There is nothing too special about the map in particular. It is a choropleth where media markets are coloured by the game being aired yesterday. (The piece explains the blackout rules that changed a few years ago from what I remember growing up.)
But then on the inside, the article takes up another page, this time fully. It runs maps down the side to highlight the matches and scenarios the author discusses, reusing the same map as above, but because this is an interior page, in black and white. It probably looks even better online as they likely kept the colour. (They did. But the maps are smaller.)
Overall, I really enjoyed the piece and the maps and visuals not only drew me into the piece, but helped contextualise the story.
