METHOD AND DEVICE FOR VISUALIZING HIERARCHICAL DATA BY USING ANGULAR CHART, AND INTERACTIVE METHOD AND DEVICE FOR VISUALIZING ANGULAR CHART (METHOD FOR VISUALIZING HIERARCHICAL DATA BY USING ANGULAR CHART, AND INTERACTIVE METHOD AND DEVICE)

摘要

PROBLEM TO BE SOLVED: To provide a method and device for visualizing hierarchical data, including a plurality of levels, by using an angular chart.;SOLUTION: One of the plurality of levels in the hierarchical data is determined as a base level. A data unit in the base level is visualized by using the angular chart. Each slice corresponds to the data unit in the hierarchical data. When the data unit in the succeeding level corresponding to the operated slice in the hierarchical data is visualized in response to the operation of a user with respect to the slice of the angular chart, the data unit in each level of the hierarchical data is hierarchically and clearly visualized even when the hierarchical data has the multiple levels or the multiple data units. Consequently, a problem that the angular chart seems to be disordered is solved, thereby allowing the user to customize angular chart visualization. Moreover, the angular chart is interactively visualized.;COPYRIGHT: (C)2008,JPO&INPIT
