matplotlib, perhaps?: http://matplotlib.sourceforge.net/

He he, it's even easier to draw a graph using the turtle module.

Uhm, that is a misconception.
Just do
turtle.hideturtle()
turtle.tracer( 0 )
to turn off the animation stuff.
That said, the turtle module bundled with Python is somewhat limited, but for
plotting simple graphs it's certainly simpler than using tkinter directly.
Cheers & hth.,
