Force Directed Graph by using Processing

Force-directed graph drawing (Wikipedia)

Force Directed Graph is one way to visualize Node-Link data by using force-directed layout algorithms.
The example below is using Coulomb’s Law and Hooke’s Law (and Damping effect) to calculate the kinetic energy of the graph that is to be minimized.
