Forgot to comment on this: Yes, it would be highly desirable to
represent polygons with centroids. In fact, many people (including the
GIS team here) would argue from a cartographic point of view, a data
element (absolute value) is best represented with a point symbol,
whereas choropleth maps should be used mainly for relative values,
i.e. indicators.
