User Quote

"DX is a very valuable tool for the Visualization Community. Having it available for education would make an outstanding contribution to any visualization or scientific computation course. I strongly believe it would serve as an excellent teaching aid and should be used in scientific visualization education."

Data Explorer in Action

Data Explorer is used to visualize matrices at the Matrix Market. The Matrix Market provides convenient access to a repository of test data for use in comparative studies of algorithms for numerical linear algebra. The visualization called Cityplots provides a quick visual check on the sparsity pattern of the matrix, as well as on the relative magnitude of matrix entries. For each matrix entry a 3-dimensional bar (a 'building' in the 'city') is drawn with it's height and color linearly scaled to the magnitude of the value. This work was done by Robert Lipman at National Institute of Standards and Technology (NIST).
