About
The TableLens by Rao and Card (1994) is an excellent example of a simple, yet expressive visualization method that can help in analyzing even larger volumes of data. This TableLens features two-tone pseudo coloring and a hybrid SOM clustering. Two-tone pseudo coloring can communicate larger volumes of data while still maintaining precision. The hybrid SOM clustering helps to extract and communicate complementary structural information about the data and also serves to drive interactive information drill-down.

You may try out this Java software. Download the file TTTL.zip and if you are lucky you can (still) run it out of the box by calling java -jar TTTL.jar on the command line. On high-resolution displays, you may want to insert -Dsun.java2d.uiScale=2.0 right before the -jar switch with a scaling factor that matches your device configuration (e.g., 2.0 for 200% display scaling). This research prototype is provided "as is" without warranty of any kind.
