Abstract: A unique method and system is disclosed for organizing and visualizing hierarchical information. It comprises an editor and a visualization engine. The editor visually organizes information elements into hierarchy by iterating elementary (binarization) steps. The binarization step splits the information elements and a quadrangular space into two parts and associates them with each other. A user may refine each partition to unlimited depth by drilling down to new level. This way, a hierarchical structure is created which is visually grouped into levels by so-called covering sets. The visualization engine, which might work independently from the editor, renders the covering sets into quadrangular-shaped visualization spaces, visualizing compact space-partitions. Several techniques aid rendering and enhanced visualization, such as windowing, visualization rules, grids, equal and alternate splitting. Users navigate in the hierarchy by zooming or moving directions.
