Is there an Open Source java alternative to GraphViz? I'm aware of the existence of Grappa which basically wraps the Graph interface to GraphViz as an JavaAPI. However the layouting is still done by the GraphViz binaries.
I'm looking for a pure-java, open source library providing the same functions and layouting algorithms as GraphViz.
You can have a look at JUNG (Java Universal Network/Graph Framework) which has visualization and analytics functions. It's open source.
