How to draw the following graph in sagemath?

edit

If G is you graph, you can define coordinates of the vertices by using the set_pos method, see:

sage: G.set_pos?

for more details.

EDIT Having a look at the set_pos documentation, it is actually lacking meaningful examples, so here is how to use set_pos: you have to define a dictionary that associates to each vertex a coordinate (i.e. a tuple of two numbers), as follows:

sage: G = Graph(3)
sage: G.set_pos({0:(0,0), 1:(1,1), 2:(0,1)})
sage: G.plot()

Alternate solution:

sage: G=Graph([[0,u] for u in (1..7)])
sage: G.add_edges([[u,4] for u in (1..3)])
sage: G.add_edges([[u,4] for u in (5..7)])
sage: D={0:[4,2]}
sage: D.update({4:[4,0]})
sage: for u in (1..3): D.update({u:[u,1]})
sage: for u in (5..7): D.update({u:[u,1]})
sage: G.plot(pos=D)

EDIT : If you insist on the order of the nodes:

sage: Dpos=[4, 3, 5, 2, 4, 6, 1, 7]
sage: G.plot(pos={u:[Dpos[u], 1+(u==0)-(u==4)] for u in (0..7)})
