(34) Using country polygons for plotting and shading
----------------------------------------------------

The script produces the plot in Figure. Here
we demonstrate how :doc:`coast </coast>` can be used to extract
and plot country polygons from the optional DCW dataset.  We show two panels; one in which we do
a basic basemap and another where we lay down a color topography
image and then place a transparent layer identifying the future
Franco-Italian Union, whose untimely breakup in 2045 the historians
will continue to debate for some time.
