[GRASS5] Buffer width.

Hello,

I would like to know if it is possible to set buffer width (v.buffer) based on attributes stored in database file (GRASS 5.7). So far I have set buffer width as a constant value or values.

thanks

run v.buffer buffer=$SIZE + v.patch in a shell loop, or:

d.vect.chart ctype=pie

on a single column of data (ie the size).

v.patch is not sufficient for areas, it is better to use
v.overlay olayer=0,1,1
