That makes sense, I didn't realize we were allowed to stretch and bend however we want. Seems weird to be allowed to take a 3D object and contort it into 2D.

But it is not a 3D object, it is in fact a 2D object embedded in the 3D space. (So, what you are looking at is the result of an arbitrary “projection” of one into the other - a map, in mathematical terms.)
