1. A method for hierarchical visualization of multi-dimensional data, comprising:
- (a) applying a first dimension-reduction process to a multi-dimensional data set to obtain a first visualization;
(b) selecting a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization where more detail is desired; and
(c) applying a second dimension-reduction process to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.

Abstract
A method for hierarchical visualization of multi-dimensional data is provided. A first dimension-reduction process is applied to a multi-dimensional data set to obtain a first visualization. A subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization is selected. A second dimension-reduction process is applied to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.

30. A computer data signal embodied in a transmission medium comprising:
-
a first segment including dimension-reduction code to perform a dimension-reduction process to a multi-dimensional data set to obtain a first visualization; and
a second segment including data selection code to select a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization wherein the dimension-reduction code is applied at least one time to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
