Network of Chicago 77 communities. (a) Community graph for year 2017. There are 77 nodes representing communities and 204 edges connecting a pair of communities sharing a boundary with each other. The average degree is 5.3 and diameter 9. The entire network consists of one fully connected component. The darkness of color is proportional to the crime rate and size is proportional to population of each cluster. The clusters of high crime are clearly visible. (b) Three clusters of communities. Each cluster contains communities with the same range of values for three features: level of poverty, percentage of property ownership, and level of education
