1. A system for generating a two-dimensional spatial arrangement of a multi-dimensional cluster rendering, comprising: a set of stored clusters from a concept space comprising a multiplicity of clusters visualizing document content based on extracted terms, each cluster in the clusters set sharing a common theme comprising shared terms; a placement module determining an anchor point on at least one such cluster within the clusters set, the anchor point comprising at least one open edge formed along a vector defined from the center of the at least one such cluster; and arranging the clusters in the clusters set into an arrangement of adjacent clusters originating from the anchor point at one such open edge.
