[MAPSERVER-USERS] Displaying population density with Mapserver

[Ritesh Ambastha]

Dear Faldor, 

Robert is absolutely right. You will have to make different LAYERS for the
same POINT layer. But, define MAX/MINSCALE for each Layer. Change STYLE ->
SIZE values in each of the layer. You are done !!

Cheers !
