Circos -- genomic mapping and comparison tool

Although it’s not something I’d ever use, the fact that someone spent time building a tool that generates some of the most interesting and dense graphics I’ve ever seen amazes me.

Circos compares genome maps and displays their similarities and differences in numerous visual formats – http://mkweb.bcgsc.ca/circos/?

It was the software used in the graphic showing Presidential candidates' references to other candidates, as mentioned in an earlier post.
