This is the difficulty. I seems need to depend on outside tool to create piechart.
I played around a bit with kchart and oodraw (openoffice Draw). Both produce satisfying piechart but: 1) seems both does not accept data from outside file. My piechart data comes from an awk script, and I need to produce 50+ such pie chart to include into publications, type data manaually is boring. 2) kchart's export format does not include "eps" nor "svg" What tool would you suggest me to use?
