Poset plot is upside-down

Tried the following in smc

X = (24).divisors()

R = [(a,b) for a in X for b in X if a.divides(b)]

D = Poset([X,R])

D.plot()

The resulting plot is upside-down; that is "1" is at the top and "24" at the bottom. How can I fix this?

You can use

D.dual().plot()

That flips it over, but the arrows point in the wrong direction.

According to the documentation, plot applied to a poset should be bottom to top with arrows pointed up.
