DDgraph: a Tool to Visualize Dynamic Dependences


Authors: Francoise Balmas, Harald Wertz and Rim Chaabane

Abstract :

Following previous work on displaying static data dependences and experience with large sets of dependence displaying strategies, we developed a tool for visualizing dynamic data dependences.
Our prototype is based on a modified Lisp interpreter and this paper presents our evaluation of its application to a highly complex AI program. This permitted us to build efficient visualizations and to evaluate the benefits of using dynamic dependences for program understanding, debuging and correctness checking.
In this paper, we present our prototype, detailing especially the different visualizations we introduced to allow users to deal with hard to understand programs, and we discuss our findings working with dynamic dependencies.
