List of Java APIs for graph/network data structures
collections, graph, java
Solution
I searched a lot for Java Graph Library in the web for my MS thesis. I suggest you the following frameworks:
- GraphStream: it has very simple API and it's plenty of algorithms. It offers many graph structures (directed, undirected, multigraph, ... ) and many visualisation tools.
- JUNG: this framework has been around for a while, so it has robust and well-tested features. Last release was in 2010, so the syntax is quite a bit old.
Both the frameworks have many algorithms and a visualisation tool.
If you are concerned about memory and performance, and you just need the graph data structure (no algorithms, no visualisation), I would suggest AuroraGraphManager, which is the graph data structure I implemented and part of my thesis. The frameworks I suggested above weren't good for me because I had to deal with quite big graphs (up to 300 million edges).
Hope it helps!
