FORESIGHT Recommending Visual Insights
Rapid visual exploration of high dimensional data
Visual insights are grouped into classes
Bookmark & search related insights
Users can bookmark interesting
insights. Foresight supports search and ranking of
insights related to a given insight —
only those insights in the
neighborhood of a given insight will
be displayed within each class.
