Multi-Dimensional Data Visualization

Category: Data Management, Software and Web Development

Overview Historically, data visualization has been limited primarily to 2 dimensions (e.g., histograms, scatter plots). Available software packages (e.g., Data Desk 6.1, MatLab 6.1, SAS-JMPTM 4.04, SPSS 10.0) are capable of producing 3-D scatter plots with (varying degrees of) user interactivity. The author constructed their own data visualization application with The Visualization Toolkit (Schroeder, Martin, & Lorensen, 1998) and Tcl/Tk to display multivariate data through the application of glyphs (Ware, 2000). A glyph is a visual object onto which many data parameters may be mapped, each with a different visual attribute (e.g., size, color). The paper used the Multi-Dimensional Data Viewer to explore data from several psycholinguistic experiments.
