Interesting. It appears to me that I can better tell area differences between nicely shaped objects rather than long narrow objects. Is there a measure that can tell how nicely shaped an object is? The obvious one I could come up with is ratio of area of object to area of bounding circle. Closer to 1 is good. Lower than some threshold we pick is bad. I'm sure someone must have thought of this problem.
It certainly works to optimize squatter triangles over long narrow triangles, and these shapes over arcs.
Furthermore, what is this kind of chart called? How was it laid out? Is it a one off manual kinda deal.
Does this even have any advantages over a pie chart? IIRC people are not good at judging relative area at all, even circles. How much does un-wedging the pie help?
At least with a pie chart you can try to compare arc length which may be easier?

> Pies and doughnuts fail because:
> Quantity is represented by slices; humans aren’t particularly good at estimating quantity from angles, which is the skill needed.
> Matching the labels and the slices can be hard work.
> Small percentages (which might be important) are tricky to show.

This visual seems to better preserve the size of smaller markets, like Singapore and Australia. In a pie chart, they'd be indecipherable.
