This example demonstrates several neat things ...

The SAS code downloads map image tiles from OpenStreetMaps.
Those tiles are 'knitted' into a single image background for 
the SAS map.

A SAS choropleth map is overlaid on top of an image of a street map, 
and alpha-transparent colors are used to fill the choro map areas,
so you can still faintly see the street-map behind them.
(the alpha-transparency is new in v9.3).

And the legend is in 'descending' order so that the maximum
values are at the top (also a new v9.3 feature).

The title is annotated, and the legend is in a non-standard 
location (via the 'offset' option).

You can mouse over the counties to see the county name & the
number of hurricanes.

This is a good alternative to using Google Maps, without violating the
Google Maps rules, and exposing your private data to the Google servers.
