graphics on a map

Howdy,

        I'd like to draw graphical elements at specific areas on a
        map.  For instance, would it be possible to draw a pie chart
        at the center of each nation on a world map?  I'm interested
        in putting histograms, scatterplots, line graphs, etc., on
        geographical regions.

        Many thanks,

                Andy
