When we think of the map of the United States, we think only geographically. However, if we represented each state by a dot (or vertex) and connected states that shared a border with a line segment (an edge), what would the map of the U.S. look like? Download US Map Graph Theory and try to identify which dot represents which state. Then check your solutions!
