Yes, but I customized them slightly for my needs and I think I must have 
erased those customised versions...

Yep, actually much more than d.vect.chart since you can create any form 
you want (have also worked with triangles)...

I create a new vector point map (belscale in the psmap files) with the 
points placed at the spot where I would like the legend. Then it 
suffices to update the values in the attribute table to relevant values 
related to your map and to display this 'map' just like the real one...

One thing that still bothers me with bubble plot is the lack of the 
possibility to sort the bubbles so that you are sure to have the largest 
in the back...

But I would like to work on all this for a new d.thematic.points...when 
I have time again.
