Thread:Talk:Semantic Maps/Google geocharts

Hello,

I came across a map that outputs a semantic query into a Google Geocharts ("google-geochart") format.

See "Number of Utility Companies by State"

I wanted to know if this / was a standard results format included in Semantic Maps, or if this was custom-made for OpenEI, as it appears to be very useful.
