Graphics.Rendering.Chart.Plot.Pie

A basic pie chart.

Pie charts are handled different to other plots, in that they have their own layout, and can't be composed with other plots. A pie chart is rendered with code in the following form:

values :: [PieItem]
values = [...]
layout :: PieLayout
layout = pie_plot ^: pie_data ^= values
       $ def
renderable = toRenderable layout
