Starstruck and doubled over: losing poise over Indian charts

Twitter follower @ashwink_s didn't see eye-to-eye with the following charts that appeared in an Indian publication. There is the infamous racetrack chart: In the racetrack chart, the designer has embedded data in the angles at the center of the concentric circles but the visual cues point to the arc lengths. If the same proportion of people voted Yes as voted No, the two arcs should look like this: The length...

Visualizing electoral college politics: exercise in displaying relationships between variables

Reader Berry B. sent in a tip quite some months ago that I just pulled out of my inbox. He really liked the Washington Post's visualization of the electoral college in the Presidential election. (link) One of the strengths of this project is the analysis that went on behind the visualization. The authors point out that there are three variables at play: the population of each state, the votes casted...

Wheel of fortune without prizes: the negative report about negativity

My friend, Louis V., handed me a report from Harvard's Shorenstein Center, with the promise that I can make a blog post or two from it. And I wasn't disappointed. This report (link) caught some attention a few months ago because of the click-bait headline that the media is "biased" against Trump in his first 100 days. They used the most naive definition of "bias". The metric is the amount...

What do we think of the “packed” bar chart?

Xan Gregg - my partner in the #onelesspie campaign to replace terrible Wikipedia pie charts one at a time - has come up with a new chart form that he calls "packed bars". It's a combination of bar charts and the treemap. Here is an example of a packed barchart, in which the top 10 companies on the S&P500 index are displayed: What he's doing is to add context to...

Reorientation in the French election

Financial Times has this chart up about the voters for the National Front, which is Marie Le Pen's party. I find the chart very hard to decipher, even though I usually like the dot plot format. The first thing to figure out is not visual. It's a definition of the data. The average voter represents those who voted in the 2015 regional election. The National Front voters are those who...

What does lying politicians have in common with rainbow colors?

Readers in Charlotte, NC: I am coming your way on April 19. Drop by and say hi. More info on my lecture here. *** Daily Kos printed this chart about the lies that candidates told: (see original here) This is an almost great chart. A color make-over improves readability significantly. What does lying politicians have to do with rainbow colors? Avoid.

Your charts need the gift of purpose

Via Twitter, I received this chart: My readers are nailing it when it comes to finding charts that deserve close study. On Twitter, the conversation revolved around the inversion of the horizontal axis. Favorability is associated with positive numbers, and unfavorability with negative numbers, and so, it seems the natural ordering should be to place Favorable on the right and Unfavorable on the left. Ordinarily, I'd have a problem with...

Butcher: which part of the leg do you want? Me: All of it, in five pieces please

This ABC News chart seemed to have taken over the top of my Twitter feed so I better comment on it. Someone at ABC News tried really hard to dress up the numbers. The viz is obviously rigged - Obama at 79% should be double the length of Trump's 40% but not even close! In the Numbersense book (Chapter 1), I played the role of the Devious Admissions Officer who...

Chopped legs, and abridged analyses

Reader Glenn T. was not impressed by the graphical talent on display in the following column chart (and others) in a Monkey Cage post in the Washington Post: Not starting column charts at zero is like having one's legs chopped off. Here's an animated gif to show what's taking place: (you may need to click on it to see the animation) Since all four numbers show up on the chart...
