Force-directed layout算法的实现
Force-directed algorithms can be easily adapted and extended to fulfill additional aesthetic criteria. This makes them the most versatile class of graph drawing algorithms. Examples of existing extensions include the ones for directed graphs, 3D graph drawing, [6] cluster graph drawing, constrained graph … See more Force-directed graph drawing algorithms are a class of algorithms for drawing graphs in an aesthetically-pleasing way. Their purpose is to position the nodes of a graph in two-dimensional or three-dimensional space so that all … See more Once the forces on the nodes and edges of a graph have been defined, the behavior of the entire graph under these sources may then be simulated as if it were a physical … See more The main disadvantages of force-directed algorithms include the following: High running time The typical force-directed algorithms … See more • Cytoscape, software for visualising biological networks.
