Data Desk's dynamic plots and tables show patterns and structure among several variables. Rotating plots and sliders use animation to reveal aspects of your data that static plots cannot show. Changing the color, symbol and selection state of datapoints instantly changes all plots to show patterns, clusters, and outliers. Hot Set selections restrict displays to subsets of your data with a single click.
GGobi is an open source visualization program for exploring high-dimensional data. It provides highly dynamic and interactive graphics such as tours, as well as familiar graphics such as the scatterplot, barchart and parallel coordinates plots. Plots are interactive and linked with brushing and identification.
Exploratory Data Analysis and Exploratory Modelling Analysis
Modern, innovative software enables not only true Exploratory Data Analysis but also Exploratory Modelling Analysis, that is the reviewing and comparison of multiple competing models of data. MANET is primarily designed for EDA, but also gives an overview of many models through graphical analyses of residuals. TURNER offers many tools for exploratory investigation and manipulation of contingency tables, but its strength is the flexible comparison of loglinear models. It is a major aim of the department to extend the ideas underlying Exploratory Modelling Analysis.
Voyager is a project to explore the feasibility of a portable and extensible system for simulation and data analysis systems. The Voyager project is carried out by StatLab Heidelberg. All components of Voyager are intended to be open for the public domain.
Added: Voyager is included in the recent distributions of the Oberon operating system from ETH Zürich.
A survey article is published in the Journal of Computational and Graphical Statistics, Volume 5 No 3 (1996) 263-283. Voyager has been demonstrated at Compstat 94.
