Flawed pie chart with too many categories, unhelpful colors

AllMusic had a recent poll asking readers about their favorite Beatles album. Interesting topic but the pie chart used to display the results didn’t work out so well:

Two main complaints:

1. There are a lot of categories to represent here:14 different albums. While it is relatively easy to see some of the larger categories, it gets more difficult to judge the proportions of the smaller categories.

2. There are some categories clearly bigger than others but the color scene seems to have little to do with the actual album title. The palette runs from black to light gray but it does not appear to be in any order. For example, they might have used the same palette but light gray would have been Please Please Me while the darkest color could have been Past Masters. As it currently stands, the reader has to pick out the category and then try to figure out where it is in the key.

Given this comes from an app intended to help create infographics, this one isn’t so great as it suffers from two issues – lots of categories and a limited color design – that I often warn my statistics students about when using pie charts.
