This "works", for some value of "works".

G = my_cool_graph
u = my_special_vertex
HL = []  # height list
for h in range(G.diameter()+1): # for height in the range
HL.append([(v,h) for v in G if G.distance(u,v)==h])
# enumerate makes this work, but don't flatten the whole thing
HL = flatten([list(enumerate(hl)) for hl in HL],max_level=1)
HL = [(v[0], (i,3*v[1])) for i, v in HL] # rearrange in an ugly way and make the heights visible
HD = dict(HL) # need a dict to make a position dict
G.set_pos(HD) # here we go
G.show(figsize=15)  # acceptable but needs centering of each row to be really nice


Do you think this would be worth adding as an option for positioning or something? It seems so ugly to me.
