Force-directed layout算法的实现
WebApr 19, 2016 · If called when initialising the force like so: var force = d3.layout.force () .charge (-100) .linkDistance (3) .size ( [width, height]) .nodes (data.nodes) .links (data.links) .start (); the layout will randomly initialise the nodes by default. The way I found of getting around that is by adding an on tick event and start the force later. WebFeb 7, 2014 · As pointed out by dirkgently, VTK has a force directed graph layout.
