Viewpoints software allows interactive visualization of multi-variate data using a variety of standard techniques. The software is built exclusively from high-performance, cross-platform, open-source, standards-compliant languages, libraries, and components. The techniques included are:

  1. Linked two-dimensional and three-dimensional scatterplots with dynamic brushing.
  2. Marginal histograms with dynamically adjustable bin size.
  3. Standard normalizations such as minmax, rank, logarithmic, sigmoidal, and Gaussian.

Viewpoints may be used with extremely large data sets. Viewpoints can be downloaded at: .
