A method and apparatus are provided which present hierarchical data to a user via a graphical user interface. A preferred embodiment represents hierarchical data related to a computer network and is provided to a user as part of a network management software application. In the interface, hierarchical data is represented by nodes, beginning with one or more top nodes and extending into lower hierarchical levels by the display of child nodes, child's child nodes, and so forth. The arrangement of nodes on the graphical user interface is such that scaling portrays the various hierarchical levels, and nodes do not spatially interfere with one another. Navigation through the hierarchical data is provided by allowing the user to select any visible node, at which point a zoom-in or zoom-out view to the selected node as a centrally located node on the interface is performed. Child nodes at lower hierarchical levels that were not visible before selection are then made visible up to a predetermined number of levels within the hierarchy. A map is provided on the interface which allows a user to graphically comprehend the present location of all nodes displayed on the interface in relation to their position within the overall hierarchy. As applied to network management, the interface allows errors in low level devices within a network to be visually propagated up to the upper levels of the hierarchy, for display to a user viewing only the top levels. The interface and computing system configured according to the invention overcomes problems of prior art systems which obscure a user location within a large hierarchy and the invention overcomes significant navigation problems of prior art systems.
