Checkered Tree: Interactive Toolset for Flexible Data Exploration

The fact is that in many Visual Analysis tasks are often used various mapping methods and techniques, inherited from the pre-computer era. Even for Data Exploration, despite of advanced interactive features of modern hardware and software. These ways of graphical representation with a static design are often rigidly adhered to a specific data structure. With such advantages of compact illustration for print (where paper space is crucial), the statically charts are principally at disadvantage in compositional flexibility. Unlike a paper version, array of interactive capabilities plays an important role in chart implementation for screen displaying. The paper reviews an original approach to categorical data visualization, which takes into account features of the visual perception of form and color, as well as distribution and focusing characteristics of the visual attention, along with advantages of using the interactive computer graphics capabilities.
