beginning with one or more top nodes and extending into lower hierarchical levels by thedisplay of child nodes, child's child nodes, and so forth. The arrangement of nodes on thegraphical user interface is such that scaling portrays the various hierarchical levels, andnodes do not spatially interfere with one another. Navigation through the hierarchicaldata is provided by allowing the user to select any visible node, at which point a zoom-inor zoom-out view to the selected node as a centrally located node on the interface isperformed.
