JGraphEd

This web page describes JGraphEd, a Java Graph Editing application and Graph Drawing framework. JGraphEd was designed to allow users to easily create graphs step by step by adding or removing, or modifying nodes or edges. JGraphEd is modular by design and a variety of standalone and interdependent algorithms have been provided for manipulating or visualizing graphs. JGraphEd was also designed with extensibility in mind, in order to allow developers to quickly and painlessly add their own algorithms to the included library.

JGraphEd was developed by Jon Harris while studying in the School of Computer Science at Carleton University.
