I've thought of doing such a thing:

http://sourceforge.net/p/gnuplot/mailman/message/26788631/

Although it isn't a type of plot I'd use in my field, it would be a 
really nice feature given how common this type of geographical "plot" 
with data points is today.  A command syntax is going to be the 
difficult part.  Defining the maps is another issue.  What if boundaries 
change?  Is there some type of universally accepted data format or 
descriptive language for map boundaries these days?
