A three-dimensional graphical user interface (GUI) that enables the navigation of an unstructured list of data elements. The invention has the following features: (a) the data elements are classified within the leaf-nodes of a hierarchical categories node tree; (b) the engine for building the GUI requires only the following two attributes per data element: (i) a text string indicating the category path, and (ii) a URL for accessing the data element; (c) the invention enables implementation of an XML application Program Interface (API); (d) the GUI displays one hierarchical level at a time; (e) all aggregate elements are presented with paths are implied; (f) each level displays all matching sibling category nodes; and (g) any displayed category node can be "drilled-down" to the next lower hierarchical level of the category tree or drilled out to immediately access the data element. |
