Interactive glyph graphics of multivariate data in psychometrics the software package gauguin

Gauguin (Grouping And Using Glyphs Uncovering Individual Nuances) is statistical data visualization software for the interactive graphical exploration of multivariate data using glyph representations. Glyphs are defined as geometric shapes scaled by the values of multivariate data. Each glyph represents one high-dimensional data point or the prototype (average) of a group or cluster of data points. This paper reviews the capabilities, functionality, and interactive properties of this software package. Key features of Gauguin are illustrated with data from the Programme for International Student Assessment.
