Abstract: A user interface is provided that displays hierarchical and/or relational information, such as information related to the topology of a computer network. The user interface provides a set of enclosed shapes arranged to present a set of nested regions to a network administrator. Each nested region represents a level of a hierarchy, and each region is segmented to represent individual elements within the hierarchy level. In one embodiment, the outmost ring is segmented to represent various networks. The middle ring is segmented to represent various subnets, with the arc of each network segmented to represent one or more subnets associated with a corresponding network. The innermost ring includes elements that represent individual data element. Connections between data elements are shown with lines extending across a shared interior region. In various embodiments, the lines may be given colors, animations, or patterns to indicate various properties of a relationship.
