- pic of horrid "word features" chart
- why is it bad?
- releases occur chronologically, but the data is displayed in a clockwise fashion with no obvious starting point
- the pie chart has no values on it at all, so we are left staring at the chart trying to guess the relative sizes of the slices
- the chart is 3D
- which makes it extra bad for estimating relative sizes
- 3D pie charts are simply an abomination
- making them 3D just makes them even harder to interpret
