The graphic was created by User:Schutz for Wikipedia on 26 August 2007, using the R statistical project. The program that generated and exported the graphic is given above; the uploaded version was generated by converting the EPS file generated by R to SVG format using pstoedit command. The layout was slightly modified using Inkscape before upload.
