Facet Key
Filtering documents by shared attributes

Facet Key shows the most frequent entities of various types across an entire document collection. Selecting an entity of interest filters and highlights linked visuals in ways that enable document collections to be analyzed systematically, one entity at a time.

An additional benefit of the Facet Key is that it can be used to create and interpret icon mappings in other linked visuals. Icons can also be customized using Font Awesome CSS class names for even more visual awesomeness.
