Visualisation and Analysis of Relationnal Data by Considering Temporal Dimension

Visualization based on graph drawing allows the identification, the evaluation of passed and present structures between actors and concepts. It also allows the deduction of future ones. VisuGraph is developed in order to offer to the users the visualization and the interactive classification of relational data. We propose to complete this prototype with a morphing algotihm which animates with fluidity the representation between different time periods, emphasizing major elements and significant tendencies.
