Abstract:
A logical zooming method for a directed graph, in which a plurality of hierarchical nodes are connected by arcs, comprising a step of:displaying said hierarchical nodes utilizing a plurality of hierarchy levels, each one of said hierarchical nodes being displayed at a location in said graph which corresponds to one of said hierarchy levels; logically zooming in on a specified one of said hierarchical nodes; and displaying said specified one of said hierarchical nodes and ones of said hierarchical nodes that are logically near said specified one of said hierarchical nodes differently from other ones of said hierarchical nodes, each one of said hierarchical nodes continuing to be displayed at a location in said graph which corresponds to said one of said hierarchy levels, wherein after said step of logically zooming, each one of said hierarchical nodes remains displayed in a same one of said hierarchy levels in which said one of said hierarchical nodes was displayed prior to said step of logically zooming.
