The amount of data that must be collected for one to decide on a course of action, nowadays and in any field, is nothing if extraordinary. The three-dimensional graphic representation of data is a powerful tool for its analysis. And the possibility for interaction and browsing throughout these data makes this analysis much more interesting and productive. Nevertheless, one doesn't usually make a decision alone, and most tools are of a single-user nature, which jeopardizes the decision-making process, especially if those involved are distant from each other, geographically speaking. With a collaborative information visualization environment, it is possible to debate over the same data and change them if necessary, in real time, diminishing time and avoiding mistakes in the decision-making process. Therefore, this paper proposes a Web-based collaborative tool for data visualization using Java, EAI (external authoring interface) and VRML (Virtual Reality Modeling Language).
