Graphs have always played a central role in the study of hyperplane arrangements. Continuing this tradition to the study of hypertoric arrangements on a torus, we study certain toric arrangements that come from graphs. Several classical results that we have extended to toric graphic arrangements include a counting of proper (divisible) colorings, formulas for (arithmetic) Tutte polynomials, and connections to acyclic orientations.

I will consider two types of toric graphic arrangements; one that lives inside the torus that arises from the root lattice of type A, and one from the weight lattice of type A.
