The application, among other things, act as a graphical interface for the popular graphviz package.The Plugin adds a Graphviz View that will display a DOT file. included (download it for Eclipse 3.2 or for Eclipse 3.3). Now I have a multi-platform, open-source and up-to-date implementation that is on par (at least for the way I use it) with the best existing platform-specific solution, and it even has my favourite editor and versioning, etc.It provides an AJAX-enabled interface to create and manage graph, node and edge styles, aswell as CCK fields to allow utilizing them for generating styled graphs. This module works as a companion to the Graphviz Filter module which integrates the versatile GraphViz tool (=> graph visualization) with Drupal.
