Comment (by jmantysalo):
If the name of variable to save the (undirected) graph is `P`, then it is
easy to just say
{{{
d = DiGraph()
d.add_vertices(P.vertices())
pos = P.get_pos()
for e in P.edges(labels=False):
if pos[e[0]][1] < pos[e[1]][1]:
d.add_edge(e)
else:
d.add_edge([e[1], e[0]])
P = Poset(d).canonical_label()
}}}
to convert it to poset. But really somebody should expand the code to
handle digraphs.
