How to draw floating pie charts on an existing plot with matplotlib

Question

I would like to plot multiple pie charts over an existing plot using absolute coordinates.

I went through the add_axes method and also the AxesGrid toolikt but couldn't find a solution.

To be more specific, I want to draw pie charts over a geographical map using the basemap module.

This tutorial explains how to use matplotlib Basemap for drawing pie charts on a map. It is fairly simple and gives code examples.
