[Cartoweb-users] circles proportional

[c.baume at voila.fr]

Hello,
I currently seek to create circles proportional of the one of my projects CW3.  
I found a message concerning this subject on http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0305/msg00525.html 
But the modification of the code other than the mapfile remains a mystery for me 
One as did me by as the functions of analysis set of themes in cartoweb3 are in project...  
Have a solution?  
sincerely 
Christophe
