PRISMA is an information visualization tool based on multiple coordinated views to explore multidimensional datasets using the following techniques: treemap, scatterplot and parallel coordinates. PRISMA is extensible, portable and easy to maintain since it has been developed in Java using design patterns.
Treemap: The user can set the attribute representing each rectangle size and color.
PRISMA uses a single dataset for all views. The user may analyze data in each view individually or simultaneously in all views. Coordination between techniques is static, i.e., the coordination of each air of views is pre-defined. Color, for instance, is strongly coordinated since the same color is defined for all views. Size, on the other hand, is loosely-coordinated since it may be used in the scatterplot and treemap views but needs to be explicitly specified in each view. Other coordinated tasks are filter, selection, and details on demand.
Details on demand
PRISMA also includes:
- Pie, Line and Bar graphics
- a report generator
- a export data function
However, the user general evaluation of PRISMA was very good. At the end of the test, users were able to indicate many prominent applications in different professional and non-professional fields.
