dynamic symbols, eg bar graphs or pie charts

[thomas bonfort]

hi all,
I'd be interrested in having/adding  pie charts or bar graphs to mapserver,
in order to output thematic maps...
I've experimented with Tim Schaub's hack for pie charts which is very nice
but a bit too cumbersome for large datasets, and was wondering if this could
be natively done by mapserver...
Could this fit in the symbology methods of MS, by defining a new type of
"dynamic symbol" which would resemble a pixmap symbol except that the pixmap
is generated from the input data?
I'd be willing to give a shot at this if you folks think this is worthwile.
cheers,
tb
