  Visualization techniques are well developed for many problem domains, but
these systems break down for datasets which are very large or multidimensional.
Techniques for data which is discrete rather than continuous are also less well
studied. Astronomy datasets like the Sloan Digital Sky Survey are very much in
this category. We propose the extension of information visualization techniques
to these very large record-oriented datasets. Specifically, we describe the
possible adaptation of the ``Visage'' information visualization tool to
terabyte astronomy datasets.
