Example of one class network. Each node is a student, connected by directed ties that represent a close friend nomination. The thickness of each tie represent strength, where 1st order nominations are weighted twice as much as 2nd order nominations. Larger node sizes denote in-degree, or more nominations. The color represents clusters, as determined by a community detection algorithm.
