Cluster Map displays clusters of related documents in an expressive image mosaic. Clusters can be arranged in a symmetric “spiral” layout or a more freeform “relational” layout, with cluster proximity in the latter case determined by the relatedness between clusters. Selecting a cluster in either layout can filter and highlight other visuals.
Cluster Map is a great way to help users navigate a report by providing a visual means of selecting everything related to a certain topic and quickly browsing a large variety of content.
