Radek: Agreed. But pie charts do have a useful place in data analysis and cartography when used judiciously. On a map, they become an effective "small multiple," which is something Tufte strongly advocates! –  whuber Mar 14 '12 at 17:16
    
Agree with whuber. Pie charts can be ok, if they're used for comparison. See this map for a good example. The pie charts are better in this situation than the bars because the bars have no common baseline, and the area of the pie charts is easier to comprehend than the total area of the bar pairs. –  naught101 Jul 16 '12 at 2:19

Giovannia is right. I outline the process here: http://darrencope.com/2011/11/01/qgis-diagrams-pie-charts-for-symbols/

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

Open the vector attributes and use the tool you'll find in the "diagram" tab.
