About JGraphT

JGraphT is a free Java graph library that provides mathematical graph-theory objects and algorithms. JGraphT supports various types of graphs including:

Although powerful, JGraphT is designed to be simple and type-safe (via Java generics). For example, graph vertices can be of any objects. You can create graphs based on: Strings, URLs, XML documents, etc; you can even create graphs of graphs! This code example shows how.

JGraphT and JGraph

JGraphT and JGraph are two different libraries which are intended for different purposes.

JGraphT:

JGraph:

The two libraries are complementary and can be used together via the JGraphModelAdapter provided by JGraphT; this adapter allows a JGraphT graph data structure to be used as the model being viewed and controlled via JGraph.
