The Improvise project at the University of Wisconsin-Madison aims to provide an end-user visualization builder and browser that employs coupled coordination and visual encoding mechanisms. With a point-and-click interface, users can create visualizations seamlessly. The current implementation is built on Java 1.4, is platform-independent, and comprises approximately 246,000 lines of code. Our goals include building an initial user base, gathering usability feedback, understanding coordination architectures in visualization, and exploring metavisualization's integration possibilities.

Presentation Transcript

  1. ImproviseChris WeaverUniversity of Wisconsin—Madisonhttp://www.cs.wisc.edu/~weaver/improvise/ • End-user visualization builder and browser • Coupled coordination and visual encoding mechanisms • Integrated metavisualization • All point-and-click operation • Fully-implemented (but by no means complete!)

  2. Implementation Trivia • Formerly Java 1.1 + Swing • Recently started changing over to Java 1.4 for Java2D, transparency, etc. • Anticipating Java 1.5 for better runtime compilation support • Xerces for document persistence • ~246,000 lines, 2900 classes (1000 fn ops) • Nominally platform-independent

  3. Hopes for Today… • Build initial user base, solicit usability feedback • Better understanding of the role of coordination architectures in visualization infrastructure • Elicit feedback about metavisualization & possibility of incorporating it elsewhere • Add my big-vis-system implementation experiences to the stewpot
