Isn't this resorting to algebra to fix the visual proof? How do you fix it visually?

You do it 3 times, a=b, a<b, a>b.

.. now that I think about it, the "visual proof" only 'proves' the statement for a specific 'a' and 'b'. Probably there is a proof, that can handle all 'a' and 'b' pairs at once.
