Collaboration is one way to deal with the increasing amount and complexity of information available to analysts. However, most information visualization systems incorporate little or no specific support for collaboration. Reimplementing existing applications to fully incorporate our current understanding of computer-supported cooperative work could be exhausting, time consuming, and expensive. To aid this process, the authors explored how to cost-effectively create a colocated collaborative information visualization and analysis environment. They extended NodeTrix, a social-network-analysis tool, to enable multiuser interaction in collaborative environments, and performed a user study assessing the retrofitted system's usability. Their results verify the low-cost retrofitting's effectiveness and highlight implications for practitioners. This article is part of a special issue on collaborative visualization.
