This is an experiment with data display based on a hierarchy of classes similar to the DOS directory-subdirectory-file hierarchy. For this demo I am using data on dog breeds and organizations in Texas. The applet is reading in a specially formatted text file. Use a mouse click to expand-contract a class. When the left panel has the focus, you should also be able to use keyboard arrow keys. If nothing appears after the data file is loaded, try clicking on the left panel.
