Abstract: A method and system for the interactive visualization and examination of data displays a set of data with graphics primitives, corresponding to attributes of the data set, in a rendered visualization. The set of data is arranged in the rendering with data items grouped in a set of ranges of data values, referred to as buckets. A user can interactively select a sub-set of the set of data and the visualization is re-rendered with the ranges of data values re-sized to display the selected sub-set with finer granularity.
Abstract: A navigation system and method for viewing a data landscape in an information visualization system employs constraints and positions for the rendering viewpoint which are defined relative to a bounding box enclosing objects within a volume of interest. The bounding box is resized to reflect changes in objects within the volume of interest including the addition or deletion of objects and/or the resizing of objects. The bounding box is also correspondingly repositioned whenever the volume of interest is repositioned. Constraints and/or positions defined relative to the bounding box are updated accordingly and are employed to control the movement and re-orientation of the rendering viewpoint within the volume of interest by the user.
