This is an old revision of the document!
The documentation available for prefuse is quite sparse, it consists mainly of the JavaDoc API documentation and demo source code. Even though the demo source code provides as good starting point (cp. [Heer et al., 1995] ), in my opinion the examples are overly complex for beginners.
Therefore, this tutorial starts with the minimum source code to create a scatter plot and incrementally adds features. Further, it discusses an axis-based visualization technique, whereas the documentation of prefuse focuses on graph visualization.
