Welcome

Viski is a Software Engineering Project at the University of Helsinki in the summer of 2006. The aim of the project was to develop a Java-based library for scientific visualization.

Our implementation is an extended version of JFreeChart. The project team developed two new visualizations:

• Hierarchical Clustering
• Self-organizing Map

The team also developed a panel for combining several JFreeChart objects into a single group, much like the ChartPanel implementation already included in JFreeChart. Unlike ChartPanel, however, our implementation allows the user to save the entire collection into a single image file or print it.

The following visualizations were considered but left out due to time constraints:

• 3D Scatter Plot
