Pie charts are already a terrible visualization, this is way worse. You're supposed to compare the area of these half circle shaped rotated slices easily? Should have just used a bar chart, in fact why wouldn't you use a bar chart? You could just have a single box and illustrate the percentage amounts by dividing the box up into different colors to indicate the percentages of a whole, but this? Nope. Tufte would probably not be pleased.
