33. An article of manufacture comprising a storage medium containing instructions that when executed enable a system to: generate a tile for each node of hierarchical information; arrange tiles for nodes of a same hierarchical level into a planar layer; arrange the planar layers in a vertical stack; generate a three dimensional orthographic projection with the vertical stack of planar layers each having multiple tiles; render, in a user interface, the three dimensional orthographic projection of the vertical stack of planar layers, wherein the vertical stack of planar layers each has multiple tiles for presentation on a display; and move a planar layer to a top layer of the vertical stack when selected.
