1. A system for reorienting a cluster rendering within a display, comprising:

  • a collection module to obtain a plurality of clusters that have been visually rendered on a two-dimensional display to model independent spatial orientations within multiple dimensions, wherein the clusters individually represent thematically related objects comprising a collection of documents;

    an evaluation module to evaluate the spatial orientations of the clusters in each such dimension by identifying two-dimensional relationships for pairs of the clusters;

    a search module to determine a distance for at least one such cluster from a common origin within the display that visually preserves the spatial orientation of the at least one cluster as a function of the relationships of that cluster, wherein the distance for the at least one such cluster is proportionately adjusted according to the relationships, and the adjustment is determined using a coefficient calculated according to the equation comprising;
