POV-Ray is an unbelievable tool, but a charting package or a CAD package it is not. It's mostly used for static art and animation. IMHO, charts shouldn't have to worry about camera position and light sources. However (OT), I have long toyed with the idea of making a Perl module to build POV-Ray files in a clever way, as well as to automate POV-Ray, but this is more of a module idea than anything else.

If this is to be done manually (and only a few times), some really basic drawing program will be easier than POV (POV has a learning curve), and I suppose the reason this was posted in a Perl forum is because he would like to generate these tables automatically as some sort of schema or definition changes, or maybe there are a lot of schemas to generate.

Of course, the POV version could use the new radiosity features and would definitely be really shiny. Be sure to include lots of textured camels.
