I am surprise because graph is different it should n't because the
adjacency matrix is the same ?
They are:
sage: W = graphs.WheelGraph(4)
sage: H = Graph(W.adjacency_matrix ())
sage: W == H
True
However, for almost every built-in graph or graph family Sage also
knows some "nice" way to draw it. For other graphs it tries to found a
"nice" drawing by partly randomized algorithm.
You can also try
H.show(layout='planar')
