Abstract:

The Delaunay system supports a visual language that is specifically geared to the querying and visualization of databases. In this paper, we concentrate on the information visualization capabilities of the system. A distinctive feature of Delaunay is its full personalization capabilities: users can define their visualizations from scratch without limiting themselves to pre-defined visualization modes. Fine customization of the visualization is achieved by the availability of a visual alphabet of atomic graphical symbols and by the expressive power of the visual query language, which supports recursion.

We describe the key components of the Delaunay system, namely its interface modules, which support advanced visualization techniques and principles, and its efficient constraint solver. The successful implementation of Delaunay demonstrates the feasibility of a powerful database system with which users can effectively specify a wide variety of visualizations supporting data and visualization exploration for different kinds of applications including graph visualization and business analysis.
