Thanks, that a step, but how do I tell matplotlib where to then put this map?
It needs to be on the current figure with the current axes but between 0 and 1
in radius.
Imagine this plot but the black circle instead contains a map of the earth as
seen from space in the right viewing geometry.

I can work out the geometry and all but putting the map in that black region
has me baffled.
