For dynamic bubble sizes saved into a vector file you would need
v.extract + v.buffer + v.patch in a loop.

For displaying dynamic bubble sizes only use "d.vect.chart ctype=pie"
with only one data column and the sizecol= option.

For displaying dynamic bubble sizes in ps.map use the vpoints
instruction with the sizecol modifier. This one lets you have
dynamically sized .eps and icons (new in 6.1-cvs). icon=basic/circle
gives you bubbles.

I hope one day to have icon= and sizecol= added to d.graph (d.mapgraph
fixes and functionality need to be merged before d.graph gets anything
new). Was there a sizecol= patch for d.vect posted recently?
