Tool Name Reference
Spotfire  For info:
Licensed software: Installed in HCIL1(3174) in the PCs called: Denali, Glacier, Point Lookout, Yosemite and Bigbasin (they all have a Spotfire mouse pad!)
REMEMBER: you do not have priority access to those PCs!

You can also download a mini demo version from the spotfire  website to try it (no save though...)

We do have a 3 y.o. Java tool called Stardom that does the basic functions of spotfire and can be used in your final project.  For the code: ask Catherine

For reference: here is the old classic demo of the HomeFinder
(PC-DOS demo)


You can request access to the Java code from Anne Rose (rose@cs) and create data for the treemap.


Several demos online 
The Java code is available in our archives, but it is now old code (ask Catherine for it). The above web page indicates how to create the data for it.

Jazz (zooming user interface)
A robust general tool for developing zoomable graphical 
applications, and of course visualizations too.
Java source code, examples etc.
You could also "draw" your viz. ideas with Kidpad.
