Google Maps exporter plugin for Gephi. This plugin exports graphs from Gephi for use with Google Maps API. Using Google Maps API it is possible to represent large graphs in real-time.
The plugin will export an example index.html file with required JavaScript functionality for loading Google Maps canvas. Google Maps functionality is fully customizable.
Example of a huge graph: http://graphmap.net/mapper
