Visual DocVizor - Version 3.20 DocVizor allows developers to quickly visualize and document the class structure of C++ code by generating a color-keyed diagram of a project's class hierarchy. DocVizor can automatic generate html files with the class information, and even generate a whole html help project file for you . Produce class-level documentation by exporting the class hierarchy for each individual class as a graphics file. You can paste the graphics files into reports, system documentation, and even web pages.
