It is important to be able to provide a variety of ways of visualising any data set if the differences between users in terms of ability and preferences are to be successfully overcome. Human variability is a wonderful thing; except perhaps when there is a visualisation being evaluated! There is not likely to be a representation that fulfils the needs of any given group of users and still remains likeable to them all. This provided the impetus to create a visualisation framework that is able to a variety of
visualisations and data through a service mechanism. This allows for matching services to be located, and utilised, as necessary, using a contain clie3nt application that acts to hold the component parts of the framework together. This provides representations each user is happiest with to be employed (of those made available), and also for a
comprehensive analysis and understanding tool because of the multiple sources of data that can be integrated. In order to best exploit the possible distributed nature of visualisations and data sources, and to provide extensibility for collaboration and Grid integration the
implementation make use of Jini.
