The positions of New York and Chicago do not correspond to their geographic locations on a map. However, this does not mean that the graph is drawn incorrectly.
This graph is not intended to show where a team is located on a map. The graph shows the number of games that each team plays against each other. The specific position of each vertex on the graph does not matter.
