any API for handling graph? in java

Question

I would like to use the concept of MindMap http://en.wikipedia.org/wiki/Mind_map

in a AI program. Is there any API for java? A good api for drawing and manipulating graphs with enough documentation and examples will also do the job.

I dont actually need to represent it graphically , i just need to build the map in any method(used for representing graphs, ) and search in it.

The program shall take a word as input

Search the mindmap for it and display the relevant words.

Answer 1

JGraphT was possible solution for me. I am working on it

Answer 2

Have you tried FreeMind? It's an open-source Java MindMap framework.
