As volume of data is growing every day, the development of data visualization and organization tools becomes more and more useful, especially when data are dynamic. We propose to use multi-agent systems to develop such tools. Data visualization is performed as visualization of reactive agents and of their interactions in their environment. Each agent takes charge of a part of information and has rudimentary means of communication via its environment. The aim of this thesis is to show how by using agents with behaviors based on ethological models (social insects), information is organized on the screen. First, we show how the introduction of attractive and repulsive behaviors succeeds in data organizing and screening. Next, we present a new way of information synthesis and hierarchy thanks to agent groups. The OSCAR framework has been implemented in order to have a generic multi-agent core. It complies with requirements of both multi-agent simulations (definition of aggregation behavior, virtual pheromone, etc.) and information visualization interfaces (take charge of and visualize dynamic data, user interactions, etc.). LEA is an application based on OSCAR. It visualizes an electronic mailbox. Each agent takes charge of an e-mail and it finds a place in its environment according to its interactions with the other agents. These interactions evolve with the user's interests. Dynamics come from two elements : first, new messages arrival modifies the organization; second, the user may personalize the agents, in real time.
