Example of a pie chart, along with a bar plot showing the same data and indicating that the pie chart is not the best possible chart for this particular dataset.

The graphic was created by User:Schutz for Wikipedia on 27 December 2006, using the R statistical project. The program that generated the graphic is given below; the data and the idea are from w:Image:PieCompare.png by w:User:Chrispounds. The graph was exported in postscript format, converted to SVG using the pstoedit command, and the layout was slightly modified using Inkscape before upload.

iThe source code of this SVG is valid.
