Some things I like (wink, wink):
- The colors get darker the farther out from the radius you go. I guess you could say they radiate.
- The pie doesn't start at the zero degree mark for easier ranking/comparisons.
- The level of precision...people must really care about the 1/10,000th of a percent of an award.
- What takes the cake, I mean pie, is the interactivity. You have to try it out; it's worth the giggle.
Don't fret. There's more pie on the buffet:
Nobel Peace Prize Winners by Gender (I like how this chart sort of "swirls" in when the page loads...fancy stuff!)
Nobel Prize Winners in Physics by Gender (The 1.0695% of women who won are probably more upset about this pie chart than any apparent sexism.)
I will give ChartsBin some credit though. Their interactive maps are quite good. They're very similar to the maps on Google Analytics.
