- Parallel Coordinates has a better chance of doing the job than any other
- methods I am aware of. I am not sure if they have been used to display
- regions of hyperspace per se, but they do well for visualization of
- hyperplanes ((N-1)-flats) as well as points (0-flats) and (N-2)-flats which
- are contained in them. Try Inselberg's papers to get started, and the first
- several chapters of my dissertation. A recently posted bibliography is
- attached below.

- All the best,

- And of course, no reference list about representing multidimensional data
- would be complete without Parallel Coordinates... :) If you need a general
- method that can represent multivariate relationships in N dimensions, I
- would recommend taking a good look at Parallel Coordinates. The papers by
- Inselberg are the best place to start...
