How Many MIT Researchers Does It Take To Screw Up a Visual?
I have no punch line, because this quick sketch by krees.left me speechless. Going way too far in support of a bad metaphor. Wouldn’t some kind of probability plot or histogram have been easier to read? Like
Speaking of MIT, sort of
Well, they got some of the the medal counts wrong, but there are other problems.
I’ve reduced their stacked donut wedge structure to a simpler pie chart.
Look okay, until you realize that there were more than eleven countries earning medals. Here is the entire list.
Hmm, about a third ov the medals were unaccounted for, and there’s no indication of that in the chart. In this bar chart I’ve lumped the missing 1/3 of the medals into an “Other” category.
Another problem with the Axiis chart is shared by all pie-type charts. The points have no common reference point: the starting points of each angular measure starts where the previous measure ends. Can you tell from the Axiis chart whether the US won more gold, silver, or bronze medals? Did China or Russia win more silvers?
Plot the data in a boring old bar chart, and ask the same questions.
Much easier to make comparisons.
The software itself looks interesting, but judging from this and other samples, there seems to be no guidance to help the user avoid ineffective chart designs.
Bill Gates Does TED
Bill Gates poses a couple of problems for us to solve. How do we eradicate malaria, which is one of the three largest contributors to childhood deaths, and how to we transfer good teaching practices from the top 10% of teachers to the rest, in order to bring the US back to parity with thee best in the world.
