Counting faces of graphical zonotopes

It is a classical fact that the number of vertices of the graphical zonotope ZΓ  is equal to the number of acyclic orientations of a graph Γ . We show that the f-polynomial of ZΓ  is obtained as the principal specialization of the q-analog of the chromatic symmetric function of Γ .
