The basic idea is to minimize the energy of the system by moving the nodes and changing the forces between them. ![]() The attractive force is analogous to the spring force and the repulsive force is analogous to the electrical force. In this algorithm, the nodes are represented by steel rings and the edges are springs between them. The idea of a force directed layout algorithm is to consider a force between any two nodes. The Fruchterman-Reingold Algorithm is a force-directed layout algorithm. A more detailed definition can be found HERE. ![]() I created a simple graph ( path_graph) and I played with Fruchterman-Reingold algorithm to position graph’s nodes.įruchterman-Reingold is an algorithm that attempts to produce aesthetically pleasing, two-dimensional pictures of graphs by doing simplified simulations of physical systems. ![]() I took advantage of this update to test NetworkX with GeeXLab. An update (1.0 RC1) has been released few days ago and you can grab the package HERE. NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.
