Circular Charts

Pie and donut charts encode proportional differences among a set of numeric values as the angular extent and in area of a circular slice.

This radial plot uses both angular and radial extent to convey multiple dimensions of data. However, this approach is not perceptually effective, as viewers will most likely be drawn to the total area of the shape, conflating the two dimensions. This example also demonstrates one way to add labels to circular plots.
