[GRASSLIST:1363] pie charts

[mlennert at club.worldonline.be]

Hello,

I would like to create a map with proportionate pie charts, i.e. in my 
particular case I'm studying the arrival of asylum seekers in Belgium 
according to the land of origin and the place of arrival (airport or land). I 
would like to create a map which uses pie charts whose area is proportionate 
to the total number of arrivals (that is possible with ps.map), but in which I 
can have to "pieces" of pie which indicate the proportion of each arrival 
point.

Anybody have an idea if this is possible with GRASS ? Or a way to integrate 
pie charts made with another program with a GRASS vector boundary map ?
