I am trying to make a map in QGIS 2.0.1 ( running on my Mac OS X Maveriks) with the proportionally sized (graduated) pie-charts. I have started with the csv conversion to kml just to place my sample sites on the map, and I am wondering if I can just modify this csv adding some extra columns indicating i) sample size and ii) percentage of each sector for the pie chart. Or there is much less complicated way?
Ok, after a few hours I found a solution:
Hope it will save someone's time struggling with mapping in QGIS.
