So in this network, the edge A, H, appears in the projection because both A and H are fans of Team 1, and the edge J, E, appears in this network because they're both fans of team 4. If you are modeling a street network, the edge data could contain timeseries data about congestion. Some users have grown to like Edge and use it regularly. A connected component is a subset of nodes where: Every node in the subset has a path to every other node; No node outside the subset has a path to a node in the subset; Let's break the graph a little more. edu Computer Science Department University of Puerto Rico - R o Piedras May 22, 2015 Abstract NetworkX is an open source project for complex networks for the Python programming language.
