This Plugin is in a very early stage of developement. So, don't use it if you aren't a developer or tester!
First version of the plugin will be attached as soon as it follows the coding standarts. Untill then use the version of the piwik-hackers mailinglist.
Keywords: GeoIP, Map
great idea to develop such a plugin! Is there any ongoing development here?
Thanks & bye
It appears the demo, mentioned in the mailing list message, does not work anymore unfortunately: http://piwikdev.christianrockt.de/index.php?module=GeoIPosm&action=getGeoIPMap
For reference, I've attached Christian's code.
