Need a java library for visualization that support automatic layout

Question

I need a java graph library for visualization that I can incorporate in my own application. I found that jgraph is excellent for visualization but require explicit positioning of the nodes. Is there any open source java graph library that support automatic layout. Any suggestion will be really helpful for me.

Answer 1

There are numerous packages to do that. If you are used to graphviz, then you may like Grappa, which is a sort of graphviz library for java (though not as complete as the original).

jung is also quite good, providing various layout engines.

Another tool of interest to build nice graph visualizations and animations is prefuse. It it very flexible, and can lead to very good looking visualizations, with complex layouts.

All of them are java libraries, and open source.
