The method of claim 1 , wherein an entity node of the multipartite graph corresponds to an entity type selected from the group consisting of: a person; a document; a project; a topic; an activity; a date range; a company; an address; and a phone number. 3. The method of claim 2 , wherein providing the first relationship visualization comprises generating a date-centric relationship visualization by: determining a visualization position for an entity node, which involves: determining a position along a first axis for the entity node based on an entity type for the entity node; and determining a position along a second axis for the entity node based on a date associated with the entity node; and generating a visualization that displays contextual information for the entity node at the corresponding visualization position.
