VisuGraph: Un outil d'exploration de données relationnelles évolutives

Visualization based on graph drawing is a powerful tool to analyze relational information evolution. It is based on big data corpora synthesis. It makes it possible to identify and to evaluate passed and current structures, and to deduce the future ones between actors and concepts. In this context, IRIT SIG team propose the strategic data analyzes platform Tetralogie and the gate Web Xplor dedicated to on line relational information navigation. VisuGraph tool adds to these two tools visualization and interactive relational data classification. We add to VisuGraph a fluid animation of graph representations of various periods, while emphasizing visually major elements and significant tendencies. We develop this approach while insisting on data structure, software ergonomics, graph drawing optimization and its animation.
