yWorks is proud to announce the availability of it's Java Graph
Visualization and
Layout Library 'yFiles version 2.2'.
yFiles can be used to create 100% pure Java applications that can
create, edit, analyze, visualize, and automatically layout diagrams,
networks, and all other types of graphs.
The new release contains a number of new layout algorithms as well as
the infrastructure for visualizing and laying out hierarchically
grouped/nested graph structures. Also, a powerful and sophisticated edge
routing algorithm has been added that automatically reroutes edges in
orthogonal fashion without producing edge or node overlaps.

Take a look at the homepage of the library yFiles:
