==========
Bar of pie
==========

Make a "bar of pie" chart where the first slice of the pie is
"exploded" into a bar chart with a further breakdown of said slice's
characteristics. The example demonstrates using a figure with multiple
sets of axes and using the axes patches list to add two ConnectionPatches
to link the subplot charts.
