I really like what the designers did here. First and foremost the key chart is a ranking chart showing the popularity of languages since 1988—Java and C have consistently been at the top. But other languages no longer relevant are not even shown. (Where are you, Actionscript?) Those that are both relevant and also mentioned are colour coded within the set.
But the truly nice thing is being able to use the empty space of the lower-left area of the chart to add some context. It shows the growth in Google searches since 2010 in searches for Python.
Bonus note, look at that rise in R since 2008.

Last Thursday, Facebook’s share price plunged on the news of some not so great numbers from the company on its quarterly earnings report. The data and number itself is not terribly surprising—it is a line chart. But what I loved is how the New York Times handled this on the front of the Business section on Friday morning.
I found the layout of the page and that article striking. In particular, each day of the share price is almost self-contained in that the axis lines start and stop for each day. I question the thickness of the stroke as something a little thinner might have been a bit clearer on the data. However, it might also have not been strong enough to carry the attention at the top of the page. As it is, that attention is needed to draw the reader down the page and then down across the fold.
Additionally, the designers were sensitive to the need to draw that attention down the page. In order to do that they kept the white space around the graphic and kept the text to two small blocks before moving on to the interior of the section.

For those of you not baseball fans, Tuesday is Major League Baseball’s trading deadline. By that evening, trades of players between teams are sort of over for the year. (Yes, I understand this is the non-waiver deadline and the waiver deadline is at the end of August, but that is complicated to explain.) And so as the end of July approaches, trades can reach a frenetic pace as teams try and fill the holes in their rosters before the playoffs begin in October.
Thankfully the folks over at Cut 4 put together a flow chart to help teams figure out how to fill those needs.
Of course by this point, a number of these players have already switched sides. In terms of design, this is more like a Friday post. Just enjoy it.

For those of my readers in Europe, Africa, Asia, Australia, and South America, you are in for a treat tonight as you get to experience the longest lunar eclipse of the year. For those of us in North America, i.e. Canada, the United States, and Mexico, we get nothing.
So for a reminder, we turn to this nice piece from Vox that explains a lunar eclipse and why they are not as common as one might expect.
The piece uses illustrations like these from Vox and supplements them with graphics from NASA. The whole piece is worth a read, especially if you enjoy space things.
Enjoy your Friday, and if you live anywhere but North America, enjoy your lunar eclipse tonight.
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.
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.

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.

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 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.
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.

Yesterday, space nerds were alerted to the news that 12 new moons have been discovered in orbit of Jupiter. These are much smaller than Jupiter’s moon Ganymede, which is the largest moon in the Solar System and is larger than even Mercury. The point is that there are almost certainly no Ganymede-esque moons orbiting Jupiter that remain undiscovered.
But despite their small size, these moons do have some interesting features, as the article I read in the Guardian pointed out. The most interesting is the orbit of the moons. In general, Jovian moons orbit either prograde, i.e. with the orbit of Jupiter, or retrograde, i.e. against the orbit of Jupiter. The two inner moons discovered are prograde and nine of the other 12 are in an outer orbit of retrograde moons. But Valetudo, the 12th, which orbits in the retrograde group, actually orbits in a prograde fashion. The graphic below from the Carnegie Science Institute does a pretty good job of showing this.
Ultimately this means that at some point in the future, Valetudo will slam head-on collision style with another Jovian moon. And reportedly that will be so intense we will be able to see it from Earth. Bangin’. Catch is that it will not likely happen anytime soon.
As for the graphic above, I am of two minds. I generally like the use of colour. The bright green contrasts starkly against the red—though it should be pointed out it would fail a red-green colour blindness test. And then the interesting, but admittedly less interesting prograde and previously discovered Galilean moons are in more muted blues and purples, which puts them further into the background. It works nicely as a complete package.
But should it be on a deep blue background? Lots of space visualisations use black backgrounds, including mywork and the workofothers. But sometimes work that uses a white or otherwise light background could more clearly show things like orbits. It is difficult to say with certainty because of the lack of a light background for comparison’s sake.
The other thing that gets to me is the viewing angle of the orbits. Clearly we are looking neither dead-on nor from high above. And that makes it a bit more difficult to compare orbits. Of course these might not all be on the same plane because orbits are in three-dimensional space. But if the orbits were all shown from above, it would certainly aid with problems of foreshortening.
All in all, though, I shan’t complain because we have more moons in the Solar System. And who knows how many more smaller moons both Jupiter and Saturn have.

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.
