In this talk I'll report on work with Matthew Hin. What is the Euler characteristic of a graph? What is the genus of a graph? More basically, what is the cohomology of a graph? We define the cohomology of any finite graph, and provide an effective algorithm computing such. Our method involves graph associahedra and toric geometry.
