Each dot represents a file changed in a darcs commit. The more changes are made to a file the bigger the dot gets. The files float around the developer's name who submitted the patch. Different colors are different parts of DokuWiki:

• red = core code
• yellow = GeSHi
• magenta = parser code
• white = test cases
• green = template and plugins
• blue = language files
