Consider a directed graph and a positive integer k. Then the number of directed walks from node i to node j of length k is the entry on row i and column j of the matrix Ak, where A is the adjacency matrix.

Force-directed graph This simple force-directed graph shows character co-occurence in Les Misérables. A physical simulation of charged particles and springs places related characters in closer proximity, while unrelated characters are farther apart. Source: http://bl.ocks.org/mbostock/4062045

Springy-Springy is a force-directed graph layout algorithm. It means that springy uses some real-world physics to try and figure out how to show a network graph in a way that looks good. Springy.js is designed to be small and simple. It provides an abstraction for graph manipulation and for calculating the layout and not too much else. http://getspringy.com
