I'm looking for a way to create dot maps (or bubble maps) out of site
data. Something like d.sites but the size of the icon should be relative
to the attribute of that site. Is there anyway to produce such maps in
Grass ?
Greetings

Don't use a big word where a diminutive word will suffice.

You can use v.circle (look at the man page), but you need first to
split your site file, because v.circle use a fixed value for radius.
This should not be difficult with a script (shell or perl) and the
use of s.out.ascii, sort, grep, s.in.ascii, v.circle to automate the
process (programming is left to the reader as an exercice
You may prefer to look at the source of v.circle and modify it,
so it can use the value to determine the radius... (Yet another
good exercice of programmation
