Summary

Dot plot showing the death rates per 1000 in Virginia in 1940.

The graphic was created by User:Schutz for Wikipedia on 28 December 2006, using the R statistical project. The program that generated the graphic is given below; it is based on the example provided with the help page of the R dataset dotchart (accessible using the command help(dotchart)), and was slightly modified to improve the result. The graph was exported in postscript format, converted to SVG using the pstoedit command, and the layout was slightly modified using Inkscape before upload.
