fillcolor=none  and go by outer ring  :-/
ISTR some code to sort them was committed somewhere..

I see the New York Times often has nice bubble plots for their maps.
They make the fill color semi-transparent, then stacked bubbles are
darker where they overlap. PostScript won't "do" transparency, so
perhaps something to look for in the grass7 display drivers.
