Don’t Do This At Home…

In fact, don’t do this ever. Today’s bad chart comes from the Philadelphia Mayor’s Office of Transportation and Utilities. I saw it and could only shake my head and wonder why.

Something more like this much more easily communicates the story.

The International Arms Trade

One of the possible set of sanctions against Russia by the United States and European Union would impact the country’s defence industries. This chart by the Economist shows how that might not have the most impact. Most of Russia’s arms exports go to China, India, and Algeria. None of whom are the United States or European Union.

Clearly I don’t love the pie charts. I would much rather have seen segmentation within the bars. Or a full-on Sankey diagram. But, the story is still worth telling.

Mobile Data Visualisation

Today’s post is not news-related for a change. (Don’t worry, I’ll likely get back to that next week.) Instead, we have a new collection of mobile data visualisations curated by Sebastian Sadowski. You can choose to see either smartphone or tablet visualisations and then filter by visual form.

Happy Valentine’s Day

To celebrate, here’s a cropping from an infographic about breakups. From a whole series of graphics about breakups. You can thank me with some dead and rotting flowers.

The Future of Data Visualisation

Happy Friday, everyone. According to xkcd, I am failing the future test. That is to say, by 2019, I will be unable to communicate data through infographics or create data visualisations.

Coffee Pie Charts

Fear not, this graphic makes about as much sense as the title. The concept is actually a worthwhile exploration of the variation in caffeine across cups of coffee from different cafes and coffee shops. But, this visualisation fails at showing it.

Remember, pie charts show the piece amongst the whole. What is the whole in this case? A cup of coffee? No, the data labels indicate milligrams per fluid ounce. It appears as if 60mg./fl. oz. is the whole. A bit arbitrary that. So what happens if you lose the trite pie as a cup of coffee device and simply chart the values. Oh wait, that’s not very hard to do. (I also threw in what I believe to be the benchmark for an average cup of brewed coffee, though I could be wrong.)

Much clearer. More concise (I used less than the original’s dimensions).

16 Useless Infographics

Happy Friday, everyone. Today’s post comes via colleagues of mine in London, who shared with me the Guardian’s selection of 16 useless infographics. They are shit infographics. Well, at least one is. Check them out and you’ll understand.

New Data Visualisation Forms

Monday was an odd day, both 1 April and the start of baseball. I had a tough decision to make: Do I post a serious baseball-related piece or a humourous April Fool’s Day one instead? If you recall, I went for the serious baseball option. But that leaves me with Friday, where I try to post work that is a bit on the lighter side of life.

So here is EagerPies, published by EagerEyes on 1 April. It’s in the style of the EagerEyes site, a blog with posts about data visualisation. This selection is EagerPies work to improve upon Minard and the layering of data sets. But if you worry about complexity, fret not for they realised that encoding data in transparency would be a step too far.

National Pi Day

Yesterday was National Pi Day. That’s Pi as in 3.14…not as in pie pie. Unless you celebrated Pi Day with pie. In which case, way to go, you. Me, I’m more traditional. I celebrated Pi Day with talk of pie charts. But at the Wonkblog over at the Washington Post, Sarah Kliff posted about several really impressive pie charts.

My favourite was the actual advertising done by the Economist back in Philly a few years ago. Their advert was printed atop a pizza pie box. It’s the double-whammy of Pi Day: pie charts atop a pizza pie.

The image below comes from a different site about the Economist ad campaign, found here, but the link goes to the celebration of pi with pie.
