Gephi adds Neo4j graph database support (screencast)
From the webpage:
Neo4j is a powerful, award-wining graph database written in Java. It can store billions of nodes and relationships and allows very fast query/traversal. We release today a new version of the Neo4j Plugin supporting the latest 1.5 version of Neo4j. In Gephi, go to Tools > Plugins to install the plug-in.
The plugin let you visualize a graph stored in a Neo4j database and play with it. Features include full import, traversal, filter, export and lazy loading.
Warning: A real time sink! 😉
Seriously, very cool plugin that will enhance your use of Neo4j!
Enjoy!
