Abstract: A treemap generation engine enables a user of a treemap generation application to design a treemap display page by providing inputs that define the format of the treemap display page, as well as inputs that define the data to be represented by the treemap display page. Based on the inputs, the treemap generation application generates treemap display data that can be processed by a browser application to draw a treemap display page on a computer.

Abstract: A data display comprises a window that shows a tree map display having menu information surrounding a field array of differently sized and colored or shaded areas that represent product offering possibilities that conform with user criteria entered through the surrounding menu windows. A Web site that uses the display technique may receive user criteria and retrieve a portion of collected data and display it to the user, so that the retrieved data describes a data subset that is responsive to the user criteria. The retrieved Web pages may be viewed to facilitate review of product offering information, and to facilitate purchase decisions that are transmitted from the Web site visitors.

Abstract: A treemap with cells that have a minimum size so that large data sets can be clearly represented. A treemap that represents a plurality of data elements is generated, the treemap including a plurality of two-dimensional cells. Each cell represents a corresponding data element in the data set. The treemap includes a portion of a display screen assigned to a first cell so that the first cell has a size. A portion of the display screen is then assigned to a subsequent cell. The size of the first cell is adjusted in order to compensate for a size of the subsequent cell and to maintain the minimum cell size.
