I would suggest to use:
p = Plot(x**2, (x, start, end))
to be compatible with integrate and other parts in SymPy.
I mentioned this patch to Aaron at the Google Mentor Summit, but
unfortunately we didn't have time to look into it there. It is very
important to improve the plotting support, so many thanks for the
initiative. I'll try to review this soon and provide suggestions.
