PivotViewer allows the interaction with large data sets in an intuitive manner.

• new visualization type of data in topic maps
• allows fast searching in large amounts of data

• facets and and their values are dynamically generated from the topic map and made available as collection

Control elements allow easy handling of the information offered.

1. Name of the collection
2. Summary of the currently active filters
3. Sorting - the values of the chosen facets serve for sorting ("Grid View") or for grouping ("Group View")
4. Permits changing between "Grid View" and "Group View"
5. Zoom - servs as alternative to the mouse wheel
6. Searchbox - searches values of the available facets
7. Name of the facet
8. Values of the facet

As soon as a single element is chosen, the relevant detailed information is shown by double clicking or zooming.

1. Name of the item
2. Characteristics - a click on a value marked in blue sets the respective filter for all items of the collection
3. Click links to the theme page of the topic

By default, PivotViewer starts in "Grid View", but the change into "Group View" allows interesting new insights..

The individual items are now grouped on the basis of the values of the facet selected in the "Sort by" control.

The resulting chart gives a fast overview of the characteristics of the considered data. The information can be further analyzed through the setting of additional filters..
