[edit] Summary
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.
a <- c(17, 18, 20, 22, 23)
cols <- c("red", "blue", "green", "yellow", "black")
postscript("piechart.eps", paper="special", width=8, height=4)
par(mfrow=c(1,2))
par(cex=1.2)
par(font=2)
defaultmar <- par("mar")
par(mar=c(0,0,0,0)) # Margins
par(las=1) # Axis labels always horizontal
par(font.axis=2)
pie(a, init=90, clockwise=T, col=cols)
par(mar=defaultmar-c(1.7,2,2.5,1))
barplot(rev(a), horiz=T, xlim=c(0,25), col=rev(cols), border=0, names.arg=5:1, space=0.8)
