What is JGraph?
JGraph is the most powerful, lightweight, feature-rich, and thoroughly documented open-source graph component available for Java. It is accompanied by JGraphpad, the first free diagram editor for Java that offers XML, Drag and Drop and much more!
With the JGraph zoomable component, you can display objects and relations (networks) in any Swing UI. JGraph can also be used on the server-side, for example to read a GXL graph, apply a custom layout algorithm, and return the result as a HTML image map.
