I need to compute gamma functions and incomplete gamma functions. mpmath is so slow that my doctests take hundreds of seconds (and I always killed them) instead of 10-15 seconds using pari to compute such things. The mpmath main loops are pure python, there's no way it's going to be faster than even the most naive pari implementation. And Pari itself doesn't really do nice graphs (or graphs at all?); sage interfaces to pari to do nice graphs.
