what would be useful is to have some sort of "plotting engine" that is a

What you are saying is that the data needs to be rendered to a graphic
locally. I think the simplest way is to create vector based plots on the
server (I've used GNU Plot inside a CGI script) but there is a system to
pretty much what you are asking for. http://code.google.com/p/flot/
Somehow, I don't think running Gnuplot on a Arduino is feasible. ABout
all it can do is respond to the HTTP "Get" with the right page.
That's why I want to push the hard work of doing the rendering onto the
client (i.e. the browser). The comm link is fast, and an SD card on the
Arduino can hold tons of stuff, so serving a page containing 100kbytes
of Java or similar isn't a problem. But doing any computation is
probably not in the picture.
