Another day in Philadelphia, another post of Philly data visualisation work. Here we have a piece from 2015 that was updated earlier this spring. It looks at overdose rates in the Philadelphia region, including parts of New Jersey. It does include a map, because most pieces like this typically do. However, what I really find interesting about the piece is its use of small multiple line charts below to take a look at particular counties.
The piece overall is not bad, and the map is actually fairly useful in showing the differences between Jersey and Philadelphia (although why New Jersey is outlined in black and the Philly suburban counties are not I do not know). But I want to take a look at the small multiples of the piece, screenshot below.
You can see an interesting decision in the choice of stacked line charts. Typically one would compare death rates like for like and see whether a county is above, below, or comparable to the state, local, or national averages. But combining the three gives a misleading look at the specific counties and forces the user to mentally disentangle the graphic. I probably would have separated them into three separate lines. And even then, because of the focus on the counties, I would have shifted the colour focus to the specific counties and away from the black lines for the national average. The black is drawing more attention to the US line than to the county line.
I know, I know. You probably expect some sort of climate post given the whole Paris thing. But instead, this morning I came across an article where the supporting chart failed to tell the story. So today we redesign it.
The BBC has an article about MPs backing a tax on sugary drinks. Within the text is a graphic showing the relative importance of sugary drinks in the sugar consumption of various demographics. Except the first thing I see is alcohol—not the focus of the article. Then I focus on a series of numbers spinning around donuts, which are obviously sugary and bad. Eventually I connect the bright yellow to soda. Alas, bright yellow is a very light colour and fails to hold its own on the page. It falls behind everything but milk products.
So here is 15 minutes spent on a new version. Gone are the donuts, replaced by a heat map. I kept the sort of the legend for my vertical because it placed soda at the top. I ran the demographic types horizontally. The big difference here is that I am immediately drawn to the top of the chart. So yeah, soda is a problem. But so are cakes and jams, you British senior citizens. Importantly, I am less drawn to alcohol, which in terms of sugars, is not a concern.

You can rightly file this one under what the fuck, which is how I found it on WTF Visualizations. The piece appears to be some sort of comprehensive guide to minerals, nutrients, and in which foods you can find them. But, as the critique title declares, this is more like Rainbowship Enterprise. How this is supposed to be remotely useful, I cannot even begin to fathom. But, hey, the title references Star Trek, so that’s a redeeming characteristic, right? Oh wait, that was in the criticism…

Nine years after the impact of Hurricane Katrina upon the city of New Orleans, the touristy French Quarter has returned according to an article in the National Journal. However, the new New Orleans beyond the French Quarter is different from what once was. In short, the new city is whiter and more Hispanic.
And while this graphic that accompanies the piece does a fair job of showing the title, a snapshot, I wish the focus would have been on more of a comparison between pre and post, old and new.
I would not necessarily chosen the same components to tell the story. But, I really want to see more direct comparisons of even just the 2000 census and data to that of 2010.

National Geographic recently published a piece designed and built for them by Fathom Information Group. Content-wise, they looked at the historic consumption of food by several different countries. What do individual food groups contribute to the overall nutritional breakdown? For the piece this basically amounted to morphing donut charts. I get the reference, but do not care for the result.
Instead more interesting is the second main view of the piece: meat consumption. Using stacked line charts, National Geographic explores changes in consumption patterns over the last 50 years. Some countries change a bit, others not so much. But as always the best examples are called out with an explanation as to why the changes. Mexico, for example, has the story about slashes in government subsidies and economic problems as to a decline in pork consumption.
Clearly I still have issues with the data visualisation. I would much rather see the selected view isolate the selection off the common baseline. But a nice touch is the small multiples from the country selection mechanism appearing to the right.

If you missed it, last week the United Kingdom held a few by-elections. For we Americans, those are like special elections for seats in the Senate or the House that are not part of the regular Congressional elections. Anyway, the big news was that the United Kingdom Independence Party (UKIP)—think Tea Party wanting out of the European Union…kind of—won a by-election for Clacton-on-Sea (not surprisingly located on the sea) from the Tories (think establishment Republicans). UKIP almost won a by-election away from Labour (kind of think Democrats?). The former was shocking but not surprising, the latter was both.
Anyway, one of the drivers of the results was the fact that British voters are no longer consistently voting for either the Tories or Labour. The Telegraph used a nice graphic to show just how far the British two-party system has declined from its peak in 1951. The piece is not very fancy, but it does the trick.

Today’s piece is hit and miss. It comes from the World Economic Forum and the subject matter is the use of Twitter across Africa. I think the subject matter is interesting; mobile communication technology is changing Africa drastically. The regional trends shown in the map at the core of the piece are also fascinating. Naturally I am left wondering about why certain countries. Does spending on infrastructure, GDP per capita, disposable income levels have any sort of correlation if even only on a national and not city level?
But what really irks me is the content that wraps around the map. First the donut chart, I think my objections to donuts—at least the non-edible kind—are well known. In this case, I would add—or sprinkle on—that the white gaps between the languages are unnecessary and potentially misleading.
Secondly, the cities are eventually displayed upside down. Thankfully the labels are reversed so that city names are legible. However, the continually changing angle of the chart makes it difficult to compare Douala to Luanda to Alexandria. A neatly organised matrix of small multiples would make the data far clearer to read.
In short, I feel this piece is a good step in the right direction. However, it could do with a few more drafts and revisions.
Canada spends quite a bit of money on foreign aid. Last week a National Post infographic looked at the targets for that aid program and in particular highlighted Haiti, a country that has received large sums after the devastating earthquake three years ago.

This is the year of the percentages. From 99 to 47. Earlier this week, Mother Jones revealed via a secretly recorded dinner Mitt Romney as claiming that he doesn’t care about the 47% of people who do not pay income tax. He probably meant that he doesn’t care about getting their vote rather than caring for them as people, but regardless of his intention his statement did not sound good. This 47% are people who are dependent on government, or as Romney’s vice presidential candidate would say, they are “takers”. But is this true?
The great thing about news stories and infographics is that as time progresses, one has more opportunities to find data to back stories and arguments. The day of the breaking news, CNN published this simple pie donut chart. Crude, but given the breaking news it is effective.
It proves that Romney was correct, that 47% of people do not pay income taxes. But, it also proves that Romney was at best glossing over the details or at worst manipulating the people listening into thinking that 47% of people do not pay taxes. It may be only 0.9% of Americans who do not pay any taxes. Furthermore, retirees and young people often do not earn income with which to pay taxes. If retired senior citizens are “takers”, I suppose Romney does not want the elderly vote so often important to the Republican base.
But news stories evolve and more statistics become available. A few days later, the New York Times published a longer infographic piece, with below a cropping of the overall.
It expands upon the nature of the story and breaks down the actual tax burden of the American public. It is far more nuanced that Romney stated back in May (the original recording of the video). The poorest Americans do not pay federal income taxes, they have the Earned Income Tax Credit (EITC) that is designed to deal with poverty, especially amongst families with children. It is, very simply, what one would call a tax credit incentivising work. The poorest Americans, however, still must pay payroll taxes and then state and local taxes. In percentage terms, the poorest Americans pay more to their states and local governments than do the wealthiest Americans, who in turn have the greater burden at the federal level. It is worth noting that many government programmes, local schools for example, are often funded at the state and local level.
The problem with Mitt Romney’s argument on taxes is that he wants to cut taxes at the highest income brackets and cut the social safety net programmes for the lowest brackets. We already have evidence that such policies do not correlate with economic growth. They instead correlate to a worsening gap between the wealthy and the poor. Think the 1920s rather than the 1950s, 60s, and 70s.
Tax policy is worth discussing. It is worth debating. But we should do so on the facts. I cannot recall the politician who spoke these words, but as someone once said, “you are entitled to your own opinion. You are not entitled to your own facts.”

This graphic from the New York Times looks at the illegal ivory trade out of Africa and into, primarily, the markets of Asia. I think the map works fairly well in showing why certain countries are centres for the illicit industry. But the two donut charts integrated into the graphic as part of the Indian Ocean are a bit weaker.
My main problem is that the shares are a bit difficult to distinguish as arcs, especially when looking at the export countries. But the second chart with the import markets does work a little bit better. In this case there are really only three markets: China, Thailand, and Others. But the chart contains the ambiguous China or Thailand. So in theory, that demarcation could fall anywhere between China and Thailand—a point harder made if comparing simply by bars. This means that the chart really is looking at China vs Thailand that combine to 87% vs. Others. The trick is finding the break between China and Thailand. Is this chart perfect? No, but in this case I think it an acceptable use of the donut—though I likely would have treated it a little bit differently to emphasise that point.
