Last week Twitter went a wee bit crazy when Donald Trump’s son posted an image about how the Republican nominee had gained ground. Except that it turns out the image was from FiveThirtyEight and looked only at a demographic split by gender—it was what the map would look if only men voted. Suffice it to say, yeah, the Twitterverse went a wee bit crazy. Thankfully the BBC put together this really great recap with some of the best of it.
Happy Friday, all.

In politics, it is really easy and often popular to bash the federal government. Especially when it comes to its penchant for collecting taxes to pay for things. And sometimes those things are in other states than your own. But do you know how much federal money goes back to your own state? Well now you can thank the Pew Charitable Trusts for putting together this piece that explores what percentage of state budgets is comprised of federal grant money.
While the piece also includes a donut chart—because why not?—my biggest gripe is with the choropleth and the choice of colour for the bins. If you look carefully at the legend, you will see how both the lowest and highest bins use a shade of blue. That means blue represents states that receive less than 25% of their budget from federal grants and also states that receive more than 40% of their budget from the same federal grants. But if your state is between 25% and 40%, your state suddenly turns a shade of green. It really makes no sense. I think the same colour, either blue or green, could be used for the entire spectrum. Or, if the designers really wanted a divergent scheme, they could have used the national average and used that as the breakpoint to show which states are above and which are below said average.

How much does a gallon of milk cost? That, of course, is one of the classic election questions asked of candidates to see how in touch they are with the common man. But the same can be understood by enquiring whether or not they know how much a gallon of petrol or gasoline costs. And Bloomberg asked that very same question of the United States relative to the rest of the world. And as it turns out, here in the States, fueling our automobiles is, broadly speaking, not as painful as it would be in other countries.
The piece includes the below dot plot, where different countries are plotted on the three different metrics and the dots are colour coded by the country’s geographic region. But as is usually the case with data on geographies, the question of geographic pattern arises. And so the same three metrics presented in the dot plot are also presented on a geographic map. Those three maps are toggled on/off by buttons above the map.
A really nice touch that makes the piece applicable to an audience broader than the United States is the three controls in the upper-right of the dot plot. They allow you to control the date, but more importantly the currency and the volume. For most of the world, petrol is priced in litres in local currencies. And the piece allows the user to switch between gallons and litres and from US dollars to the koruna of the Czech Republic.

Yes, ISIS does receive a lot of attention in the media and during the presidential debates. But you might be surprised to learn that actually the organisation has lost a significant amount of territory lately. This BBC article details the territorial changes through a nice interactive map slider.
You could create a single map showing the losses/gains instead of using this light-duty interactive piece. And to the BBC’s credit they did. However, between the image quality and territorial changes, I think in this instance the interactive piece does add clarity to the story.

Well last night was the debate and it was a doozy. But while I was looking for some graphics capturing the debate itself, I came upon an article over on the Washington Post about gerrymandering. For those that do not know, gerrymandering is when state-level politicians draw the maps for congressional districts to preserve or diminish support for various representatives. And Pennsylvania is one of those states with a lot of oddly shaped districts.

In moving back to Philadelphia from Chicago, I have forsaken polar vortices for hurricanes and nor’easters. And this current weekend, it appears increasingly likely that the weather will be impacted by Hurricane Matthew, presently tearing its way through the Caribbean. So of course I am following projections and forecasts of just where this storm will be headed.
Thankfully Mashable has an article that attempts to explain just what the National Hurricane Center (NHC) means when it publishes its cone of uncertainty charts. Because, according to the article, it turns out most people do not entirely understand just what it means.

One of the things I like about Chicago’s WGN network is its weather blog. They often include infographic-like content to explain weather trends or stories. But as someone working in the same field of data visualisation and information design, I sometimes find myself truly confused. That happened with this piece last Friday.
The map in the upper-right in particular caught my attention and not in the good way. The overall piece discusses the heavy rainfall in the Chicago area on Thursday and the map looks at the percentage increase in extreme weather rainfall precipitation. All so far so good. But then I look at the map itself. I see blue and thing blue > water > rainfall. The darker/more the blue, the greater the increase. But, no—check out Hawaii. So blue means less rainfall. But also no, look at the Midwest and Southeast. So does green mean anything? Beyond being all positive growth, not that I can tell. As best I can tell, the colour means nothing in terms of rainfall data, but instead delineates the regions of the United States—noting of course they are not the standard US Census Bureau regions.
So here is my quick stab at trying to create a map that explains the percentage growth. I have included a version with and without state borders to help readers distinguish between states and regions.
And what is that at the bottom? A bar chart of course. After all, with only eight regions, is a map truly necessary especially when shown at such an aggregate level? You can make the argument that the extreme rainfall has, broadly speaking, benefitted the eastern half of the United States. But, personally speaking, I would prefer a map for a more granular set of data at the state or municipality level.

Today’s post features a simple set of graphics on the BBC, however the creators were actually the Asia Maritime Transparency Initiative. The background? The increasingly tense geopolitical situation in the South China Sea, where China claims numerous islands and reefs claimed by other countries—and to a smaller extent other countries make similar such claims. Just a few weeks back, the Hague ruled against Chinese claims against islands within the Philippines territorial waters. But as these graphics show, it takes more than a legal decision to effect change on the ground.
Satellite photography shows military installations on numerous Chinese-held islands. But what makes the images potent in the communicative sense is the simple overlay of white plane illustrations. They show how many fighter jets, support aircraft, patrol aircraft, &c. that China can base at the various military installations. It is a simple but incredibly effective touch.

I am on holiday for a few days and am visiting Philadelphia. So what better time to cover some Philadelphia-made content? This interactive piece came out last year from Philly.com alongside coverage of the Philadelphia mayoral contest.
I want to call out the colour palette for the choropleth in particular. We can see a blue to red system with a stop at yellow in the middle—a divergent palette. With this kind of a setup, I would expect that yellow or the light blue to be zero or otherwise straddle the point of divergence. Instead we have dark blue meaning 0 and dark red meaning 401+. The palette confuses me. It could be that the point of divergence—something around the 200 number—could be significant. It could be the city average, an agreed upon number for good neighbourhood relations, or something. But there is no indication of that in the graphic.
Secondly the colour choice itself. I often hesitate using red (and green) because of the often-made Western connotation with bad. Blue here, it works very well with the concept of the thin blue line, NYPD blue, blue-shirted police. If we assume that there is a rationale for the divergent palette, I would probably place the blue on the high-end of the spectrum and a different colour at the negative end.
Lastly, from the perspective of the layout, Philly has a weird shape. And so that means between the bar chart to the right and the city map on the left the piece contains an awkward negative space. The map could be adjusted to make better use of the space by pointing north somewhere other than up.—why is north up?—to align the Delaware River with the bars. Or, the bars could abut West Philly.
The interactions, however, are very smooth. And a nice subtle touch that orients the reader without distracting them is the inclusion of the main roads, e.g. Broad Street. The white lines are sufficiently thin to not distract from the overall piece.
I am not watching the conventions for the first time I can recall, because no cable television. But, I am occasionally dipping into live feed coverage. And while Michael Bloomberg spoke FiveThirtyEight linked to a few pieces of content they published earlier. I covered one about candidates abandoning the middle ground earlier. But this one I had skipped. It looked at the possibility of Michael Bloomberg stepping into the White House as president.
