viztool generates diagrams of collections of Java
classes. It presently has only two visualizations:
one shows inheritance hierarchies, interfaces
implemented and inner classes declared, the other,
a more detailed view of the classes, including
public fields and methods. It is structured to
allow the implementation of other visualizations.
It uses the Java 2D API for rendering, but does so
with the expectation that the diagrams will be
printed, rather than rendered to the screen
(though screen rendering is supported).
