[xwiki-users] d3js requires TopoJSON

To draw maps based on XWiki content d3js in combination with TopoJSON seems a good combination. But as d3js can be used by installing the extension d3js in xwiki there is no such extension for TopoJSON? What would be required to create a extension that works together with the frameworks in xwiki, or add the TopoJSON to the d3js extension?
