JGraphT supports various types of graphs including: * directed and undirected graphs. * graphs with weighted / unweighted / labeled or any user-defined edges. * various edge multiplicity options, including: simple-graphs, multigraphs, pseudographs. * unmodifiable graphs - allow modules to provide read-only access to internal graphs. * listenable graphs - allow external listeners to track modification events. * subgraphs graphs that are auto-updating subgraph views on other graphs. * graph visualization using the JGraph library Although powerful, JGraphT is designed to be simple and type-safe (via Java 5 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!

Cewolf
Cewolf can be used inside a Servlet/JSP based web application to embed complex graphical charts of all kinds (e.g. line, pie, bar chart, plots, etc.) into a web page. Therefore it provides a full featured tag library to define all properties of the chart (colors, strokes, legend, etc.). Thus the JSP which embedds the chart is not polluted with any java code. Everything is described with XML conform tags.
