Steps to Reproduce

see Demo or replace geo with series { type:'map', map:'USA'} in official example

Current Behavior

2D maps could be defined with geo, or with series type map, or with both. Pie charts can be positioned on geo maps, but do not show up on map series alone.

Expected Behavior

Since both geo and map series have the same coordinate system, users would expect pies to work with both. If this isn't true, then it should be at least mentioned in the API docs.
