Chart.Surface

Surface chart combinators.

A common chart is to present a set of rectangles on the XY plane with colour representing values of the underlying data; a surface chart (often called a heatmap).

SurfaceData, the rectangle and the color value, is a different shape to the usual data elements of a chart, so there is a bit more wrangling to do compared with other chart types.
