Baselines Are Important

Last week the Washington Post published a fascinating article on the data visualisation work of the Donald Trump media campaign. In my last job I frequently harped on the importance of displaying the baseline and/or setting the baseline to zero. When you fail to do so you distort the data. But maybe that is the point of this, for lack of a better term, political data visualisation.

My favourite author is George Orwell of 1984 and Animal Farm fame. But Orwell also penned numerous essays, one of which has struck me as particularly relevant in this election cycle: Politics and the English Language. In concluding the essay Orwell wrote:

Political language…is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.

And so political data visualisation? Well I believe it exists to serve the same purpose. The article goes into detail about how the designers behind the graphics fudged the numbers. Now did the campaign intend to mislead people with the data visualisation graphics? It is hard to say, because some of their graphics actually diminish leads that Trump has among certain demographics. Could it be the designer behind the graphics simply does not understand what he or she is doing? Perhaps. We clearly cannot know for certain.

Either way, it points to a need for more understanding of the importance and value of data visualisation in the political discourse. And then the natural follow-up of how to best design and create said visualisations to best inform the public.

But I highly recommend going to the Post and reading the entirety of the article.

When America Votes by Goat

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.

Pardon the Interruptions

Well that does it for the three presidential debates. Didn’t they seem very presidential with all those interruptions and interjections? Thankfully after the debate, FiveThirtyEight put together a quick graphic highlighting the total number of each per candidate per debate.

New Neighbours

Among the many, many stories that broke during my month-long radio silence, I got fairly excited about the discovery of a planet orbiting Proxima Centauri. And not just any planet, but a likely rocky planet within the star’s habitable zone. Put that all together and there is the possibility that the planet could host life as we know it. How can that not be exciting? Thankfully the Guardian put together a graphic to support an article detailing the discovery.

Beating Ted Williams

Last week the Red Sox’s season came to an end after being swept by the Cleveland Indians and with the sweep so too ended David Ortiz’s career. He is one of the best Red Sox hitters of all time, but Ted Williams was the best. And so last week FiveThirtyEight ran a piece on how one manager from the Cleveland Indians—hence the relevance, right?—beat Ted Williams by “inventing” what we all know in baseball as the shift.

The below photo comes from the game and shows what we baseball fans now think of as routine was at the time almost brand new. (Although to be fair, the shift in this case left only one fielder on the left side of the field—the left fielder. Typically today both the shortstop and left fielder both remain.) Anyway, for those baseball fans, the article is worth a quick read.

Follow the State’s Money

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.

The Price of Petrol

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.

Trump’s Support

The debate was Sunday and here we are on Wednesday. The infamous video is, well, still infamous, but not garnering as much attention half-a-week later. On Monday, the Economist published this piece taking a look at how Trump’s support shifted in the hours and days following the video’s release.

The Shrinking Extent of ISIS

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.
