ForceDirected class. Create Sandbox. The layout iteratively moves Force Directed Layout. A particle charge force that pushes elements away from each other, SNA template. d3. It's possible to link nodes not directly related with a parent-child relation. The position Verlet integration allows you to define geometric constraints (such as bounding boxes and collision detection) inside the "tick" event listener; simply move the nodes to comply with the constraint and the simulation will adapt accordingly. A force-directed graph drawing algorithm - also known as spring-embedder or energy-based placement algorithm - arranges graphs in an organic and aesthetically pleasing way. A physical simulation of charged particles and springs places related characters in closer proximity, while unrelated characters are farther I did a fork on the classic original because I found the straigth arrows to be more pleasant (especially if using a single color) by changing linkArc() and increasing the arrow length by a little using forceCollide(). repulsion: How much the nodes should push each other away.
