T Minus 12 Weeks

Today is Tuesday, 14 August. We are now 12 weeks away from the 2018 midterms. That is just three months away. Coverage will only intensify in the weeks to come, and you can be certain that if there are pieces worth noting, I will do that. But to mark the date I went with this choropleth map from the New York Times.

The nation will turns its eyes to you…in 12 weeks

Nothing too crazy here. Likelihood of results colour the districts. The darker the blue, the more solid the Democratic seat. The darker the red, the more solid the Republican one. But what this map does really well is it excludes the likely’s and the solids and sets them to a light, neutral grey. You can still hover over a district if you are curious about where it falls, but, in general those have been excluded from the consideration set because they are not the districts of the most national attention.

Secondly, note the state labels. States like Wyoming that have no competitive seats have no label. After all, why are we labelling things that have no impact on this story, again, the competitive races. Fewer labels means fewer distracting elements in the graphic.

Finally, the piece includes the ability to zoom into a region. After all, for those of us living in urban areas, our districts are geographically tiny compared to the at-large or state-wide seats like in Wyoming, the Dakotas, and Alaska. Otherwise, good luck trying to find the Illinois 5th or Pennsylvania 3rd.

Global Warming and Harder Living

The weather in Philly the past week has been just gross. It reminds of Florida in that it has been hot, steamy, storms and downpours pop up out of nowhere then disappear, and just, generally, gross. I do not understand how people live in Florida year round. Anyway, that got me thinking about this piece from a month ago in the New York Times. It looked at the impact of climate change and living conditions in South Asia. Why is South Asia important? Well, it is home to nearly a billion people, a large number of whom are poor and demanding resources, and oh yeah, has a few countries that have fought several wars against each other and are armed with nuclear weapons. South Asia is important.

I ain't moving to Nagpur, India. That's for sure. — I ain’t moving to Nagpur, India. That’s for sure.

The map from the piece—it also features a nice set of small multiples of rising temperatures in six countries—shows starkly how moderate emissions and the high projection of emissions will impact the region. Spoiler: not well. It notes how cities like Karachi, for example, will be impacted as hotter temperatures mean lower labour productivity means worse public health means lower standard of living. And it doesn’t take a rocket scientist to see how things like demand for water in desert or arid areas could spark a conflict between Pakistan and India. Although, to be very clear, the article does not go there.

As to the design of the graphic, I wonder about the use of white for no impact and grey for no data. Should they have been reversed? As it is, the use of white for no impact makes the regions of impact, most notably central India, stand out all the more clearly. But it then also highlights the regions of no data.

The Decline of the Media

Everybody loves maps. Unfortunately this is not a map to love. The Economist looked at the global status of the free press and its decline around the world.

The graphic is a neat little package of a map to anchor the narrative and a few callout countries with their general declines—or in Tunisia’s case the reversal thereof—highlighted. But I do have a few issues with the piece.

Do the lines need to be curved? Some certainly make sense, e.g. how do you get from the Turkey box to the outline of Turkey? But then for Afghanistan, a straight line through Balochistan, Pakistan would mean the line would not have to cover Pakistan, India, curve around Sri Lanka, and then finally reach the box.

In the little boxes, I also wonder if the lines need to be as thick as they are. Could a lighter stroke weight improve the legibility of the charts?

And to be super picky, I wonder if the stroke outlines of the countries are complete. My trained eye fails to register an outline of both the European part of Turkey and of the Russian oblast of Kaliningrad.

State Level Action on Gun Control

A few months ago I covered an editorial piece from the New York Times that looked at all the action, by which I mean inaction, the federal government had taken on gun violence in the wake of some horrific shootings. Well on Saturday the Washington Post published an article looking at how there has been action on the state level.

It used a series of small multiple maps of the United States with states represented as tiles or boxes. States are coloured by whether they took action in one of six different categories. It is a pretty simple and straightforward design that works well.

The only thing I am unsure about is whether the colours are necessary. A single colour could be used effectively given that each map has a clear title directly above it. Now, if the dataset were to be used in another chart or graphic alongside the maps where the types of action were combined, then colours could be justified. For example, if there was a way to see what actions a state had taken, i.e. pivot the data display, the different colours could show what from the set the state had done.

And in Pennsylvania’s case, sadly, that is nothing.

The Rising Tide of Jihadist Violence in Africa

The other day somebody mentioned to me that Africa is big, to which I agreed. It is big. It contains, depending upon how you count, about 55 countries and over one billion people. It stretches from Mediterranean climates and deserts in the north to rainforests around the equator and then back down through steppe climates to the southern coast of South Africa.

But in that vast territory also comes jihadist violence, and in this article by the Economist, it points out that despite that vastness, the violence can be found in two main areas: first, along the Mediterranean coast and, second, along the Sahel and savannah.

At least it's not spiking? — At least it’s not spiking?

The map uses dots to nice effect here, pinpointing the actual locations of violence and then providing additional detail by colouring the dots according to the perpetrators of the violence. But what I really enjoyed was the simple effect of tying together the dot colours to the stacked area chart in the lower left. It shows the number of people killer per year. And while significantly up from 2010, at least the number of people killed by Boko Haram is down from its heights in 2014–15.

But the reason I brought up the vastness at the beginning is that while these are all groups following a jihadist ideology, many are also driven by very local concerns. Consequently they likely have local solutions. And we need to be careful about how much lumping together we do about jihadist violence in Africa.

Revealing the Past Through a Heatwave

The United Kingdom has been…well, enjoying is not the right word for me, so let’s just say witnessing a heatwave. And it is having some unexpected consequences. In short, things like grass will behave differently in extreme conditions when planted on soil vs. when growing atop stone, wood, or other non-natural features. This helps identify foundations and alike for long-forgotten structures. The BBC has a nice piece looking at some work just like this discovered across the British Isles.

The house was known about, but the details are still fascinating.

Rescuing a Trapped Thai Football Team

For much of the last two weeks the world has followed the drama unfolding in Thailand, where a youth football team has been trapped underground in a partially flooded cave complex. This weekend, rescuers, who had overcome a daunting challenge of simply finding them, began extracting the boys. And this graphic from the BBC shows just how challenging their extraction will be.

In particular I like this map. It illustrates both the path of the cave, but also shows how uneven the interior structure is. It does that by showing select cross sections with a person to scale. Some parts are so small and narrow that people can barely squeeze through.

Swedish Trade

Today is a great World Cup day. The two teams for which I am rooting are playing—thankfully not yet against each other. Later this afternoon England takes on Colombia. But this morning Sweden will play Switzerland. (Neutrality is no longer an option.) And in the spirit of Sweden, I figured I would return to my winter trip to Stockholm and dig out a graphic. This one seemed particularly relevant.

It may be difficult to read, because it is in Swedish along with being large, but it shows medieval trade routes connecting Sweden to Europe. For example, Stockholm received cloth from East Anglia in modern-day England and from Bruges in Flanders, beer from modern-day Germany, and wine from modern day France and Spain.

Even in the Medieval period, international trade was vital to the economies of the emerging European cities and states.

The London Job Exodus

Brexit is bad for Britain. Here is some proof from an article by Bloomberg that looks at where London-based banking jobs are headed post-Brexit. Spoiler alert, not elsewhere in Britain. The article purports to be more of a tracker in that they will add on data about jobs moving places when news breaks. But I cannot verify that part of the piece.

What I can verify is a sankey diagram. Underused, but still one of my favourite visualisation forms. This one explores where companies’ London-based banking jobs are moving. Right now, it clearly says Frankfurt, Germany is winning.

As sankeys go, this one is pretty straightforward. Aesthetically I wonder about the colour choice. I get the blues and that the banks are coloured by their ultimate destination. But why the gradient?

But conceptually the big question would be what about London? I probably would have kept London in the destination set. While many jobs are likely to leave Britain, some will in fact stay, and those lines will need to go somewhere in this graphic.

The piece also makes nice use of some small multiple maps and tables. All in all, this is a really solid piece. It tells a great—well, not great as in good news—story and does it primarily through visuals.

Chinese Urban Clusters

Yesterday the Economist posted a graphic about Chinese urban clusters, of which the Chinese government is planning to create 19 as part of a development strategy. In terms of design, though, I saw it and said, “I remember doing something like that several years ago”.

The Economist piece looks at just the geography of the Chinese clusters. It highlights three in particular it discusses within the article while providing population numbers for those clusters. Spoiler: they are large.

The Economist graphic does little else beyond labelling the cities and the highlighting of the three features clusters. But that is perfectly okay, because that was probably all the graphic was required to do. I am actually impressed that they were able to label every city on the map. As you will see, we quickly abandoned that design idea.

The Chinese government's new urban cluster plan — The Chinese government’s new urban cluster plan

So back in 2015, using 2014 data, my team worked on a series of graphics for a Euromonitor International white paper on Chinese cities. The clusters that the analysts identified, however, were just that, ones identified by researchers. Since the Chinese government had not yet created this new plan.

We added some context to our cluster map

We also looked at more cities and added some vital context to the cluster map by working to identify the prospects of the various Chinese provinces. Don’t ask me what went into that metric, though, since I forget. The challenge, however, was identifying the four different tiers of Chinese city and then differentiating between the three different cluster types while overlaying that on a choropleth. Then we added a series of small multiples to show how now all provinces are alike despite having similar numbers of cities.

Credit for the Euromonitor piece is mine. I would gladly give a shoutout to those that worked with me on that project…but it’s been so long I forget. But I’m almost certain both Lindsey Tom and Ciana Frenze helped out, if not on that graphic, on other parts of the project.
