Many of these graphs have descriptions within them, so I encourage you to explore all of them!
Fair warning: The laggiest ones are the 3D ones (except the mesh manipulation one).
I could honestly have an entire page dedicated to all the different ways to do 3d in desmos because
I've done everything from raytraced equations to rasterized volumes, and honestly I might soon!
Also, some graphs look slightly different in the thumbnail than in the graph itself.
Anyways, Enjoy!
