Under this model, a researcher can direct system activity by specifying a particular analysis task, such as "Compare data set a with data set b. This is quite different from current practice in visualization tools, where activity is most often specified in therm of graphical entities such as raster images and color-lookup tables. The high-level task specification is combined with information about the characteristics of the data (dimensionaliity, size of each dimension, etc.) and these parameters are matched against a collection of visualization cases that the system knows how to handle. If a suitable match is found, the system retrieves the appropriate templated specification of a visual representation. The template is parameterized for this particular scenario and the display is automatically generated and presented to the user.

Researchers in the visualization community develop techniques for presenting and interacting with graphical representations of data, design algorithms for fast implementation, and build systems for integrated problem-solving environments. Researchers addressing the virtual reality aspects of these problems also explore strategies for object selection, object manipulation, and navigation within the virtual data space.
