We have a nice little piece from the Economist today, a look at the electoral majority for London-area constituencies and how their housing prices may begin to draw out priced-out Labour votes from London proper.
What I really like from the design side is the flip of the traditional choropleth density. In other words, we normally see the dark, rich colours representing high percentages. But here, those high majority constituencies are not the ones of focus, so they get the lighest of colours. Instead, the designers point attention to those slimmest of majorities and then offer the context of average home prices.

I added Chelsea to make doubly certain for my Philadelphia audience that you did not think I was referring to Philly’s Kensington. Why? Because today’s piece comes from the Guardian and refers to the neighbourhood where the Grenfell Tower caught fire and the inferno killed dozens of people.
This is not the most complex piece, but I really like the annotations and notes on the choropleth. They add a great amount of detail and context to a graphic that I imagine many places would be okay leave as is. I can see why the colour palette differs for the two maps, but I wonder if it could have been made to work as a unified palette.

I have lived in Philadelphia for almost ten months now and that time can be split into two different residences. For the first, I took the El to and from Centre City. For the second, I walk to and from work. I look for living spaces near transit lines. In Chicago I took the El for eight years to get home. But to get to work, I often used the 143 express bus. Personally, I prefer trains and subways to busses—faster, dedicated right-of-way, Amtrak even has WiFi. But, busses are an integral part of a dense city’s transit network. You can cram dozens of people into one vehicle and remove several cars from the road. Here in Philadelphia, however, as the Inquirer reports, bus ridership is down over the last two years at the same time as ride-hailing apps are growing in usage.
For those interested in urban planning and transit, the article is well worth the read. But let’s look at one of the graphics for the article.
The map uses narrow lines for bus routes and the designer wisely chose to alternate between only two shades of a colour: high and low values of either growth (green) or decline (red). But, and this is where it might be tricky given the map, I would probably dropdown all the greys in the map to be more of an even colour. And I would ditch the heavy black lines representing borders. They draw more attention and grab the eye first, well before the movement to the green and red lines.
And the piece did a good job with the Uber time wait map comparison as well. It uses the same colour pattern and map, small multiple style, and then you can see quite clearly the loss of the entire dark purple data bin. It is a simple, but very effective graphic. My favourite kind.
Anyway, from the data side, I would be really curious to see the breakout for trolleys versus busses—yes, folks, Philly still has several trolley lines. If only because, by looking at the map, those routes seem to be in the green and growing category. So as I complain to everyone here in Philly, Philly, build more subways (and trolleys). But, as the article shows, don’t forget about the bus network either.

I don’t use Reddit. But things begin to made sense for me in this article from the Economist as it explained the origins behind Trump’s weird tweet of himself beating up a CNN-headed wrestler.
I think the thing perhaps lacking from the graphic is a line that tracks Trump’s approval or popularity. The article mentions that explicitly and it would be interesting to see that track over time. Although I certainly understand how stacking so many line charts above each other could become difficult to compare.
And my final critique are the Election Day outliers. They are above the y-axis maximum. But I wonder if there couldn’t have been a way of handling the outlier-ness of the datapoints while remaining true to the chart scales.

I’m working on a set of stories and in the course of that research I came across this article from Philly.com exploring traffic accident in Philadelphia.
The big draw for the piece is the heat map for Philadelphia. Of course at this scale the map is pretty much meaningless. Consequently you need to zoom in for any significant insights. This view is of the downtown part of the city and the western neighbourhoods.
As you can see there are obvious stretches of red. As a new resident of the city, I can tell you that you can connect the dots along a few key routes: I-76, I-676, and I-95. That and a few arterial streets.
Now while I do not love the colour palette, the form of the visualisation works. The same cannot be said for other parts of the piece. Yes, there are too many factettes. But…pie charts.
From a design standpoint, first is the layout. The legend needs to be closer to the actual chart. Two, well, we all know my dislike of pie charts, in particular those with lots of data points, which this piece has. But that gets me to point three. Note that there are so many pieces the pie chart loops round its palette and begins recycling colours. Automotives and unicycles are the same blue. Yep, unicycles. (Also bi- and tricycles, but c’mon, I just want to picture some an accident with a unicycle.)
If you are going to have so many data points in the pie chart, they should be encoded in different colours. Of course, with so many data points, it would be difficult to find so many distinguishable but also not garish colours. But when you get to that point, you might also be at the point where a pie chart is a bad form for the visualisation. If I had the time this morning I would create a quick bar chart to show how it would perform better, but I do not. Trust me, though, it would.
Today we look at income in American cities and in particular the middle class disappearance. The Guardian published the graphics, but they originate with Metrocosm, LTDB at Brown, and IPUMS National Historical Geographic Information System. So what are we looking at? Well, the big one is a set of small multiples of cities and their income breakdowns as percentages of city census tracts. This screenshot is static, but the original is an animated .gif.
I have a few issues with the design of the graphic, the most important of which is the colour palette. If the goal is to focus on the decline of the middle class—and I admit that may be the point of the Guardian’s authors and not the original authors—why are the most visually striking colours at the top of the income distribution. Instead, you would want to draw attention to the middle of each chart, not the right. And if the idea was that the darker colours represent the higher income groups, well the positioning of each bar on the chart and the axis labelling does that already. After all, if anything, the story is that in a number of cities the middle class has shrunk while the lower income groups have grown. And you can barely see that with the lower income groups coloured yellow.
My other issues are more minor design things such as the city labelling. I kept reading the label as being below the bars, not above as it actually is.
And then I wonder if a different chart form would be more effective at showing the decline in the middle class. Perhaps a line chart plotting the beginning and end points for each cohort?
Then the piece gets into some three-dimensional maps that you can spin and rotate.
Yeah. Shall I count the ways? A more conventional choropleth would have served the purpose far more effectively. The dimensionality hides lower income tracts behind higher ones. The solution? Allow the user to rotate and spin the map? No, get rid of the dimensionality. It offers little to the understanding of the underlying data. Not to mention, are the areas of shadows shadows? Or are they another bin or cohort of income?
And then you have to read the piece to get a fuller understanding of my criticism.
But don’t worry, I can quote it.
Chicago was largely successful transitioning away from manufacturing to a service-based economy. This shift is evident in the bifurcated pattern present in 2015 – a heavy concentration of wealth in the business/financial district and marked decline in the surrounding area.
Those of you who read this blog from Chicago or who have lived in Chicago will pick up on it. The rest of you not so much. The concentration of wealth is not located in the business/financial district. Those dark red skyscrapers are not actual skyscrapers, they are census tracts located not in the financial district, but the areas of River North, Old Town, Gold Coast, &c. Thinking of the issue more logically, yes incomes are up in cities that are doing well. But how many of those very wealthy live on the same block as their office? Not many. Your higher income is going to be concentrated in residential or mixed-residential neighbourhoods near, but not in the business/financial district.
The data behind this work fascinates me. I just wish the final graphics had been designed with a bit more consideration for the data and the stories therein. And a little bit of proper understanding of the cities and their geography would help the text.

There is no graphic today. Why? Because I want to illustrate a point that a lot of the work I and others in the information design world depends upon data. After all it puts the data in data visualisation. But yesterday the director of the US Census Bureau resigned because the Trump administration would not meet the Census Bureau’s funding request for conducting the 2020 Census.
And that matters. Yeah, it will be bittersweet to know that Philadelphia has probably slipped behind Phoenix, but the Census and the Census Bureau do so much more than that. They collect and publish data on income, health, housing, trade, and more. And that broad and deep set of data is invaluable.
These days we joke a lot—and I count myself in that we—about alternative facts. But all kidding aside, facts matter because they should underpin any debate we can have about policy. Do you want to have a debate about immigration, well before one goes out and makes wild statements and suppositions, government statistical agencies can provide cold, hard facts about actual levels of immigration. Once we know the scale and scope of the real problem we can begin to design real solutions.
If we want to elevate our society’s discourse and move away from divisive conversations and accusations, we need to establish a common baseline around which we can debate. And observable, provable data points provide just that. If we remove those data points, we will continue to just talk past each other and into our own echo chambers.
Consequently our first step should be properly funding the US Census.
Information design takes many forms. True, in this blog I focus mostly on graphics, but signage is another important form. And the keys to signage are iconography and typography. So today we are going to take a look at some news in the typography front. Specifically, the introduction of a new typeface for Dubai designed by Nadine Chahine and Microsoft.
First, I am no expert in type design, but I dabble. Second, note that the above screenshot with its white type on black screen, each letter surrounded by keyboard shapes, is the only graphic on the website that I could easily find for a spec sheet.
The typeface does appear to have some nice letters in there and from the site it clearly reads well at small sizes. But that’s the Latin version. The real beauty in the thing is the simultaneous design of the Arabic script side of the face.
I am no expert in type design, but I do have experience setting type in Arabic as well as choosing an Arabic face for brand identity. It is really, really hard. (For the record, I found a really nice version of Avenir Next turned into Arabic.) So what I really like about this project is that it makes a nice typeface in both Latin and Arabic available to the public for free via Microsoft. Great, fantastic.
But where I get suspicious is that second point. That one graphic is the only one I could find. The site copy really pushes Dubai, Dubai, Dubai. And my cynical self wonders if the real purpose was to promote the emirate by throwing some money at design, which it can do because it has a lot of money.
Or to look at it another way, if it were not so Dubai-promotional, would it not have examples of it in use? A full character set on display?
But why am I most doubtful? Well, it does not take more than the first handful of results on the Google to bring up some less than stellar things about Dubai. What do I mean? Well, first look at the first two sentences on the Dubai Font page:
Expression is the way everyone shares their thoughts, ideas, and emotions. Writing is a form of expressing oneself and Dubai is giving the world a new tool to communicate with.
And now snippets from the first three results that are not Wikipedia (worth pointing out that Dubai is part of the United Arab Emirates and these reports are on that country as a whole):
International Centre for Justice and Human Rights
United Arab Emirates is a federal state comprising seven emirates, including Abu Dhabi and Dubai. The UAE nationals represent 11.5% of the population who number 8.5 million people. The country has seen a wave of arrests and violations of human rights and freedoms and mute the voices of dissent. The authorities are continuously and increasingly, restricting personal freedoms and freedom of speech, press, assembly and association. As practiced blatant attacks on the privacy of citizens.
The authorities continued to arbitrarily restrict the rights to freedom of expression and association, detaining and prosecuting government critics, opponents and foreign nationals under criminal defamation and anti-terrorism laws. Enforced disappearances, unfair trials and torture and other ill-treatment of detainees remained common. Scores of people sentenced after unfair trials in previous years remained in prison; they included prisoners of conscience. Women continued to be discriminated against in law and in practice. Migrant workers faced exploitation and abuse. The courts continued to impose death sentences; no executions were reported.
While the United Arab Emirates (UAE) constitution provides for freedom of speech, the government uses its judicial, legislative, and executive powers to limit this right in practice.
True freedom of expression from Dubai should not and is not about designing a new typeface, but honouring the actual idea of freedom of expression. That is to say that I may say things that you do not like and vice versa.
Designing a new typeface that works in both Latin and Arabic? Well one, where were you like eight years ago? But of almost as much importance, a clean, Dutch-inspired typeface is not going to wipe your slate clean and prevent you from ever visiting the Hague. Actions speak louder than the typeface in which you set your words, whether they’re Arabic or Latin.

Yesterday we looked at the result of, but today I want to talk about covering of the French presidential election. It dovetails nicely with a recent story here in the states about Hawaii.
Last week Attorney General Jeff Sessions criticised a court ruling because it came from a judge “on some island in the Pacific”. That island, of course, is Oahu. Oahu is one of several islands that comprise the state of Hawaii, including the eponymous island. But it does not matter that the state is in the middle of the Pacific Ocean, it is one of the fifty states of the union. And in terms of population, it isn’t even the smallest state. Should we not care about court decisions in Wyoming because so few people live there? No, because it is one of the fifty states.
Now you are likely asking, what does that have to do with the French presidential election? Well, it has to do with choropleth maps of French results. Well, most likely you were not looking at a map of the French Republic. Take this map from the New York Times.
It looks like France, but it’s only a part of France. Instead, we have France 24 presenting the map correctly. The thing missing? All those little geographies around the border.
You may recall that France at one point had an empire. At home, France was organised into state-like entities called departments. By contrast, the United Kingdom had an empire with its home territories organised into counties. Then in the 20th century, both empires began to dissolve. In the UK that meant independence for most places, but others transitioned from colonies to crown dependencies, e.g. Gibraltar and until 1997 Hong Kong. But technically, they are not part of the United Kingdom. (Don’t get me started on the Isle of Man, Jersey, and Guernsey.)
In France, there were some conflicts—here’s looking at you French Indochina/Vietnam—and some independence. But for those that did gain independence, the territories took a different track from the crown dependences in the UK. France integrated them into the French Republic and made them full-on departments. (It is a little bit more complicated than that, but for now we’ll keep it simple.) So now, if you visit Canada and take a day trip to St. Pierre and Miquelon, you are stepping on France. This is also different from Puerto Rico and the United States, where Puerto Rico is not fully part of the United States.
And so what does this mean for electoral purposes? Well, as you have probably figured out, this all means that French elections are geographically broader than those of the UK or the US. Gibraltar does not vote for Parliament and so you will not see it on the June election maps. In 2016, notice how you did not see Puerto Rico in the US presidential election maps. But because of how France integrated its former colonies as departments, Cayenne, French Guiana gets as much of a say on the French president as does Paris.
So remember, next time you look at a map of France on Europe, it’s like looking at a map of the United States without Alaska and Hawaii. Because France too exists on an island in the Pacific. It’s called New Caledonia.
Today’s post is not so much about a graphic per se, instead I read an article in the Guardian about how Boston’s public school system has decided to switch from the Mercator map projection system to the Gall-Peters projection system.
The article is worth a read if only for the embedded clip of the episode of the West Wing where they talk about the Gall-Peters. But for those of you not familiar with map projection systems, the problem is it is impossible to perfectly reproduce a three-dimensional spheroid onto a two-dimensional flat plane. Some maps sacrifice proportions for straight lines, others sacrifice shape for area, and so on and so forth.
