Papers We have Written

Here you'll find an archive of all the papers we have published that are related to Piccolo, it's predecessor toolkits, or zoomable user interfaces in general.

Our Main Paper

In general this is the publication you should cite if you would like to make reference to Piccolo or Jazz.  It is our most recent paper.  And, it represents the culmination of what we have learned through the evolution of our various toolkits.

  Toolkit Design for Interactive Structured Graphics
Bederson, B. B., Grosjean, J., & Meyer, J. (2004).
