Graphics::Simple is a module that emulates something like the graphics
API provided by Commodore-64 or VIC-20 in Perl:
        use Graphics::Simple;
        line(50,50,150,150);
        line(10,10,290,10);
        line(10,290,290,290);
        circle(50,50,25);
This can be rendered on a variety of devices, currently an X window
(using the Gnome Canvas, requiring a recent gnome and gnome-perl interface:
gnome-perl on the Gnome CVS, the CPAN module is out of date) 
or postscript.
See the pod documentation in Simple.pm for details on the operations
provided.
