Looking for web-based graph editing framework [closed]

Question

Does anyone know of a web-based framework for interactively editing graphs (nodes and edges)? Flash or Javascript is fine. I'm looking for something like GEF in Eclipse, or JGraph, or the NetBeans graph framework. Thanks!

Just to be clear, I'm interested in editing tools for mathematical graphs (nodes and edges), not charting tools.

Answer 1

There's WireIt, which has a interface that is comparable to Yahoo pipes. There are a couple examples that look to be pretty graph-oriented.
