When I was surfing, I found really good javascript based visualization tool. It is called "The JavaScript InfoVis Toolkit". It provides really good visualazitons in web browsers and free to use.


In order to have querry for the interaction visulization you just change browser adress bar text. For example,
http://string-db.org/api/image/network?identifier=4932.YML115C&
required_score=950&network_depth=2&limit=10&network_flavor=evidence
returns you
If you change the "network_depth=2" to "network_depth=3", then,
Simply you can see interaction neighborhood of any protein using correct naming and id.
