This paper describes a prototype that offers visualization features for monitoring a Web-based collaborative platform. The data displayed supports workplace awareness by providing an overview of the activities carried out on the platform. The prototype focuses on the information structured as hierarchical data. Three views are included: a classic vertical(More)
This paper proposes a method based on composite indexes to reflect the level of computer–supported cooperative activity. This approach is innovative in the sense that it extends ap urely quantitative approach with some qualitative contextual elements. Indeed, the indexes integrate two basic features of the computer-supported interactions within a group: the(More)
How to visualize datasets hierarchically structured is a basic issue in information visualization. Compared to the common diagrams based on the nodes-links paradigm (e.g. trees), the enclosure-based methods have shown high potential to represent simultaneously the structure of the hierarchy and the weight of nodes. In addition, these methods often support(More)
