Interactive graphics provides a powerful set of techniques for data exploration. While the basic building blocks are similar across software packages, there are some important differences. I will explore some of these similarities and differences using software from the GGobi and DataDesk/Augsburg "families".
Interactivity is a very important so I will use live examples with the same dataset in different programmes. I will discuss both general approaches to data and data formats, as well as specific tools unique to each program. In particular, I will discuss projection based techniques (tours, projection based small multiples) within GGobi, and the tools for examining conditional and marginal distributions (mosaic plot, spinogram) provided by Mondrian/Manet.
This is an exciting time for interactive graphics as the two families of interactive graphics are each working on a book. Freely available software is also maturing to the point that it is easy to use for researchers from a wide range of disciplines.
