		+	:It took me a while to figure this one out. I kept thinking it was representing data on two axes, like some sort of combined pie chart/polar area diagram. Like a spie chart, but working in some different, unfathomable way. But no, the radial dimension means nothing, it's just used to help clarify the borders. They took a bunch of percentages of different groups, then put them together in a bar chart, decided they didn't like how the bars looked, and told Excel to turn it into a pie chart. So it added the percentages to get a total, then divided each data point by that, and used the results to make a completely meaningless pie. It's like discovering that skim milk is 0.5% fat, whole milk is 3.5%, and cream is 36% fat: adding them up gives 40, so you make a pie chart where skim milk is 1/80 of a circle, whole milk is 7/80, and cream is 72/80. And then you gave each sector a random radius and shade of green. So, so, so dumb. [[User:EebstertheGreat\|EebstertheGreat]] ([[User talk:EebstertheGreat\|talk]]) 02:15, 8 July 2023 (UTC)
