Graphics.Rendering.Chart.Plot.Pie

Description

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
