Springy is a force directed graph layout algorithm. So what does this “force directed” stuff mean anyway? Excellent question! 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. Here's an example:Getting...

The great advantage of this type of Force-Directed graph plotting algorithm is the simplicity of its implementation.However, it works best for graphs where the number of lines is similar to the number of points. Denser graphs with many lines or unstructured graphs are less suitable. ...

yFiles provides a very sophisticated implementation of the force-directed graph layout algorithm calledOrganic Layoutthat is well suited for both small and large graphs and can easily be configured. It can avoid node/edge overlaps and supports user-specified node sizes and edge lengths. ...
Since force-directed algorithms can be extended easily, they are used frequently. Most of these algorithms are, however, quite slow on large graphs, as they compute a quadratic number of forces in each iteration. We give a new algorithm that takes only O(m + n log n) time per iteration...
The Fruchterman-Reingold algorithm is one of the most popular force-directed algorithms. It works by applying repulsive forces between nodes and attractive forces along the edges. The algorithm keeps adjusting the positions of the nodes until the graph settles into a balanced and stable layout....
Let us now move on to the force-directed graph layout problem. A basic algorithm forforce-directed graph layoutbuilds on two laws of physics:Hooke's lawandCoulomb's law. Graph nodes are imagined as points with identical electric charges repulsing each other according to Coulomb's law. Edges...
based on a force-directed approach, that preserves edge crossingproperties. This algorithm insures that two edges cross in the f i nal dra-wing if and only if these edges crossed on the initial layout. So no newedge crossings are introduced. We describe applications of this techni-que to ...
