Consider the following code:

def Sier(g):
h = Graph()
for i in range(1, g.order() + 1):
    perm = {u: (i, u) for u in g}
    gg = g.relabel(perm=perm, inplace=False)
    h.add_edges(gg.edges())
return h
f=Sier(graphs.CompleteGraph(4))
v=f.vertices()
n1=[((a,b),(b,a)) for (a,b) in v]
n2=[(a,a),(a,a)) for (a,b) in v]
x=set(n1)-set(n2)
z=f.add_edges(x)
z.plot()

The plot function does not give the graph I desire. The size() function gives the size correctly. But the diagram is incorrect. Why is this? Any workarounds to make it precise? Thanks beforehand.
