2.)
The data would be better drawn as a pie-chart.
Also wrong. Pie charts are a very bad way of representing the distribution of data within a dataset. When we scan a pie chart we're looking to see which colour looks biggest so as to determine their relative size, but since they are by nature (unless divided equally) of completely different shapes, it's very difficult to accurately ascertain how much one slice is relative to another. This problem is compounded when pie charts are given a pseudo-3D projection (as some individuals have done in this very thread), since perspective will exaggerate the relative size of an angle towards the front, and understate the size of angles at the back.
For example, take this chart that shows the win percentage for Eye of the Storm.
