Google geocharts
From semantic-mediawiki.org
Fragment of a discussion from Extension talk:Semantic Maps
This is not Semantic Maps. In fact, it's not using Google Maps but some other Google visualization tool.
Has any more happened on this? It would be very useful if the functionality of the Geochart feature within Google Charts was available. From the look of the table required for the Javascript, it is feasible within Semantic Results Format, as much as the other Google Charts features are. My little sampler is at http://jsfiddle.net/Ljraeheg/2/
I have done all the other stuff I need completely within Semantic MediaWiki including the calculations needed.
