Nitpick: Some of those pie charts are not very nice to read. Some of the busy ones have me scanning for labels left and right. A table would be simpler to read (especially as the labels are small and light grey for some reason). I think pie charts are perhaps better when you've got, say two to four items and labels are short enough to be in place instead of off to the side.
