Schedule Generator is a small Perl script that draws up a weekly schedule as a Scalable Vector Graphics image. Running it on your own computer may take some basic knowledge of how to use a command line, but the form interface on the demo site ought to be usable by anybody. It's implemented as a module rather than a standalone program so that the same code can be used in a CGI script (as on the demo site) or a Perl one-liner. It depends on the SVG module.
