What is a good plotting tool for making 3D surface graphs? My goal is to explain how if you have a curve

y = A*x^3 + B*exp(sin(3x))

you can graph x vs y but also x vs y vs A to show how varying the parameter shifts the family of curves so you can find a best fit by comparing x and y from data to x and y in your model.

I am pretty sure excel will refuse outright, I have #python I have #mathematica I have #matlab . I am fine coding, just not fidding with 1000 things to make a legible graph.
