I'd like to enlist some sighted assistance in some simple graphics art:
For our examples, I'm creating a page showing the exposure of
mathematical equations. One is textual (no problem for me), but the
other is graphical (a hurdle I obviously cannot master). So if I may,
I'd like to ask someone to create me a graphic that contains a good
representation of the mathematical equation
x^2 + y^2 + z^2 (x squared plus y squared + z squared).
Thanks a bunch!
