I want to graph a circle in 3d, but don't know the code for it. I've tried the following code, but it doesn't seem to work.

Circle is a 2D graphics primitive. The corresponding primitive in 3D would be Cylinder:
Graphics3D[{FaceForm[None], Cylinder[{{0, 0, 0}, {0, 0, 0.01}}]}]
Or use ParametricPlot:
ParametricPlot3D[{Sin[u], Cos[u], 0}, {u, 0, 2 Pi}]
You can also use Line like this:
pts = Table[{Sin[u], Cos[u], 0}, {u, 0, 2 Pi, 0.01}];
Graphics3D[Line[pts]]
