Main Functions[edit]
Treemap[edit]
Treemap: The user can set the attribute representing each rectangle size and color.
Scatterplot[edit]
The scatterplot technique is based on the cartesian coordinate system. The user can select which attributes are represented by the X or Y axis.

Selection[edit]
This figure shows the selection feature used on the starting dataset.
Details on demand[edit]
After selecting an attribute the user can gather additional information by using the details-on-demand function.
Filter[edit]
The filter dynamic interface. This function helps reducing the overload in the user interface if the dataset is very big (with the range filter in this example).

- Pie, Line and Bar graphics
- a report generator
- a export data function
Evaluation:[edit]
A usability test has been carried out with 11 persons (6 Computer Professionals and 5 General Users). Each person had to solve 4 tasks using PRISMA.
