Abstract:
A computer-implemented method of representing a hierarchical node structure on a display screen, comprising:(a) identifying a plurality of parent nodes of the hierarchical node structure that have multiple immediate children nodes, including parent nodes at multiple different levels of the hierarchical node structure;(b) displaying a parent node identified in (a) on the display screen, and displaying the immediate children nodes of the parent node around the parent node over an angular range which exceeds 180 degrees; and(c) repeating (b) for multiple additional parent nodes identified in step (a), including parent nodes at multiple different levels of the hierarchical node structure, to generate, within a single view, a two-dimensional, non-hyperbolic map in which children nodes are positioned around their respective immediate parent nodes over said multiple levels of the hierarchical node structure.
