SQiRL is a novel visualization system for querying and visualizing large multivariate data sets. Although initially
designed for novice users, recent extensions to SQiRL facilitate more advanced analysis without sacrificing the
simplicity that makes this visualization appealing to beginners. The default view provides a simple-to-learn
interface for query evaluation. Intermediate users are provided a straightforward method for comparing the
results of two queries. More advanced users can make use of a "radial crosstab," a new interactive visualization
technique that melds the expressive power of traditional crosstabulation with a drag-and-drop canvas.
