There are a couple of "ready-made graph equation visualizers" already made for Tk.

Check out the widget demo, and look for "7. Plot a series of continuous functions on a Perl/Tk Canvas.". You can easily make it a stand-alone application.

Or go to tkgnuplot and get a nice one.

That will really impress your kid. :-)
