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:
- Linked two-dimensional and three-dimensional scatterplots with dynamic brushing.
- Marginal histograms with dynamically adjustable bin size.
- Standard normalizations such as minmax, rank, logarithmic, sigmoidal, and Gaussian.
Viewpoints may be used with extremely large data sets. Viewpoints can be downloaded at: http://www.assembla.com/wiki/show/viewpoints/downloads.
