Abstract: A system, method, program product and service for navigating and displaying hierarchically structured data. A system is provided that includes: a graphical data display system for displaying a structured diagram having a plurality of nodes; a navigation system for allowing a user to launch a viewport at a selected node within the structured diagram to view subnodes of the selected node; and a context maintenance system that maintains a visual context between each of the plurality of nodes and subnodes within the structured diagram.

Abstract: A method implemented in a scalable auxiliary graph for simultaneously displaying both traditional hierarchical information and auxiliary information at the same time. The method provides for a scalable auxiliary graph that shows feature interdependencies between a selected feature or sub-feature and any related interdependent primary features and/or sub-features. Here, the scalable auxiliary graph includes a visual anchor connecting the plurality of primary features and sub-features. A visual link is used to connect a currently selected feature or sub-feature to the visual anchor. Visual connector lines are used to link the visual anchor to related interdependent primary features or sub-features. This allows the user to simultaneously visualize relationship between the selected feature and any related interdependent primary features and/or sub-features.
