Grapher

With Grapher, you can graph equations and data sets and visualize the results on your Mac in real time. Grapher displays algebraic relations, both implicit and explicit, in 2D and 3D. You can use a variety of coordinate systems and choose from a wide array of mathematical functions, including differential equations, parametric curves, and more. When you’re done, you can export your graphic as an animation that can be played in QuickTime Player.
