Hi,

Is there a v.bubble equivalent for GRASS 5.7?

I'd think it would be 'd.vect.chart ctype=bubble' but that doesn't
seem to exist.

Maybe some quick hacking on ctype=pie might work..

5.0's v.bubble breaks when bubble areas overlap. I'd think this should
have been d.bubble in the first place, but then again I guess you want
it for ps.map.

To make a new vector (for later analysis), v.buffer should be used, but it
does not support individual buffer sizes (using attributes).

To display points with different sizes only, the option should be added to
d.vect and ps.map, I think.

d.vect.chart ctype=pie with one column does not work?

thus, for export to ps.map one might use:
  v.buffer and then v.patch in a Bash loop.

for display to X/PNG monitor one might use:
  d.vect.chart ctype=pie with one column

(untested)
