How can I draw a polytope with the Graphics function? The documentation simply says that you can do it, but does not explain how. The example given only plots vertices, not the edges of the polytope. Using:

 Graphics[Octagon]

gives an error. I also tried the following from a different question:

 Graphics[Octagon & /@ Vertices[Octagon]]

and that does not work either. I also tried the following:

 Graphics[Line[{{0, 0}, #}] & /@ Vertices[Octagon]]

and that does not work either.
