"In this article I'll show you how to use JGraph, an open source, Swing-based library for creating graphs. You can use JGraph to create graphs for almost any kind of application, and it is applicable to both desktop and server-side Java applications. As an exercise, I'll walk you through the process of creating a small browser that shows a graph of a lemma and its links to other lemmata on Wikipedia. (A lemma is the word under which a set of related dictionary or encyclopedia entries appears.) When a user clicks on a lemma in the Wikipedia browser it is displayed along with its links.Once you've built the Wikipedia browser and have a good grasp of how JGraph works, I'll suggest some of the ways graphs could actually be useful to Java developers; including a graphing application to simplify the creation and management of XML configuration files."
"Last time, I introduced you to a series on useful open-source tools that could prove beneficial to your Java career. The inaugural article focused on iText, an open-source Java library for creating PDF, HTML, RTF, and XML documents. This article continues the series by presenting JGraph."
