An Information-theoretic Framework for Visualization

Min Chen

(Swansea University)

This talk is an extended version of the presentation given in VisWeek 2010 on this topic. We examine whether or not information theory can be one of the theoretic frameworks for visualization. We formulate concepts and measurements for qualifying visual information. We illustrate these concepts with examples that manifest the intrinsic and implicit use of information theory in many existing visualization techniques. We outline the broad correlation between visualization and the major applications of information theory, while pointing out the difference in emphasis and some technical gaps. Our study provides compelling evidence that information theory can explain a significant number of phenomena or events in visualization, while no example has been found which is fundamentally in conflict with information theory. These findings suggest that further theoretic developments are necessary for adopting and adapting information theory for visualization.
