[meteorite-list] Help with stewn field diagram

[David Allepuz]

Hello list,

I'm going to start drawing the strewn field of a new meteorite find.
As I have to draw 86 different positions and the 86 circles with an area 
proportional to mass....I'm wandering...Is there any soft, any aplication, 
any trick, to make this tedious job easy ?????

How do you do it?

Thank you.
