Anyone got any ideas on how to produce graphs based on a CGI query and 
     dynamically incorporating the graphs into a web page?

1. There's an apache module for doing this, I believe its called
Apache::Chart or Apache::GDGraph or something.

2. If generating a chart from querystring params isn't right for you, you
can do it yourself with one of the perl charting modules and simply send
out the binary data with a Content-Type of image/png. Of course you have
to do it from a <img> tag, or as a direct URL, but you knew that, right?

An excellent graphing engine is rrdtool, which is written by Tobi Oetiker,
who also wrote MRTG.

It comes with it's own perl modules as well.

I would just like to thank Tobi Oetiker for his excellent work with MRTG: it
has given me (the novice engineer) an unsight into my networks!
