Grapher is a computer program that has been included with OS X (now called macOS) since version 10.4 that can generate 2D computer graphics and 3D computer graphics, function graphs from simple and complex equations. It includes a variety of examples from differential equations to 3D rendered Toroids and Lorenz attractors. It is also capable of dealing with Function functions and compositions. You can edit the graphics view by changing the line colors, adding patterns to the created surfaces, adding comments, and changing the fonts and styles used to display them. Grapher can create animations from graphics by changing constants or rotating them in space.
