Abstract
Methods and apparatus are disclosed for generating animated treemaps, such as Voronoi treemaps, with node insertion to visualize dynamic hierarchical data. A treemap is processed by obtaining a multi-level tessellation having a plurality of existing regions; and inserting at least one new region into the multi-level tessellation by adjusting one or more of a size and location of at least one of the existing regions. In this manner, a stability of the treemap is preserved. The insertion selects a vertex of the multi-level tessellation as an insertion point. The selected vertex can be selected randomly from a set of vertices that define regions that are siblings to the newly inserted region; or can be a known location. A weight can be assigned to a new Voronoi generator, such as a nominal weight according to one or more constraints of the tessellation.
