Visualization really ought to be a team activity, allowing a research group to analyse a set of results collectively. However existing systems do not allow this - they are designed for the single user.
But now there is a solution. The COVISA toolkit extends IRIS Explorer into a multi-user visualization system. Individuals in a research team can create their own visualizations as normal, by linking modules into a dataflow pipeline. In addition they can now link these pipelines - on different machines anywhere on the Internet - into a multi-user visualization network. This allows a wide variety of options:
The COVISA toolkit was originally designed at the University of Leeds by Jason Wood and Helen Wright (now at University of Hull) and is described in the paper 'Collaborative Visualization' (by Wood, Wright and Brodlie) presented at IEEE Visualization97. This production version has been developed by Jason Wood, within the University of Leeds, IRIS Explorer Centre of Excellence. It is available, now, free, from http://www.scs.leeds.ac.uk/iecoe
The IRIS Explorer Centre of Excellence is a collaboration between the University of Leeds and NAG Ltd, who develop and distribute IRIS Explorer. The Web site, http://www.scs.leeds.ac.uk/iecoe has full details of the Centre including:
