Patent ID: 8041125

Claim:
A data visualization device comprising: a memory configured to store: a plurality of data input items comprising one of: a single-dimensional data value, a first attribute value corresponding to said single-dimensional value, and a function of said first attribute value; and a processor configured to: calculate a focal value of each of said plurality of data input items, wherein said focal value corresponds to one of: a single-dimensional data value, a first attribute value corresponding to said single-dimensional value, and a function of said first attribute value; categorize each of the plurality of data input items as falling within a range of focal value, selected by a user, that represents a focal region of interest to said user, or as falling outside said focal region, if a data input item is categorized as falling within said focal region, then representing said data input item as a non-cluster blob, and if said data input item is categorized as falling outside said focal region, then further categorizing said data input item according to a second attribute value of a second user-selected attribute or function of said second user-selected attribute, and clustering each of said categorized data input items corresponding to said second attribute value for representation as a cluster blob; arrange said data visualization as a radial display, wherein: said focal values extend in an order from a center of said radial display to an outermost radial extent of said radial display; and said focal region of interest comprises a contiguous portion of a radius of said radial display; and render a size of said cluster blob as proportional to a number of said data items having said second attribute value of said second user-selected attribute or a function of said second user-selected attribute.
