Abstract: Data visualization apparatuses, computer-readable mediums, computer data signals embodied in a transmission medium, data visualization methods, and digital computer data visualization methods are provided. According to one aspect of the present invention, a data visualization apparatus includes an image device configured to provide a visual image; and digital processing circuitry coupled with the image device and configured to access data including a plurality of themes, to generate a thematic illustration corresponding to the themes and having a plurality of outer contour lines which are spaced at varying distances relative to a reference line, and to control the image device to depict the thematic illustration.

Abstract: Multi-query data visualization processes, data visualization apparatus, computer-readable media and computer data signals embodied in a transmission medium are provided. According to one aspect of the present invention, a multi-query data visualization process includes inputting a plurality of query objects into a data processing device and identifying features within each of the plurality of query objects that allow comparison to a body of data stored in a database. The process further includes determining relative relationships between each of the plurality of query objects and the body of data and displaying points along a plurality of rays, wherein a position of each of the displayed points corresponds to the determined relative relationship between each respective one of the plurality of query objects and the body of data.
