Continuous ForceLink ​

algorithmsforce-layoutlayout

This example shows how to use the continuous option with the forceLink layout to create organic animations while the nodes are being layed out.

js
import Ogma from '@linkurious/ogma';

const ogma = new Ogma({
  container: 'graph-container'
});

ogma.generate
  .barabasiAlbert({
    nodes: 200,
    m0: 20,
    m: 1
  })
  .then(graph => {
    ogma.setGraph(graph);
    ogma.view.locateGraph();

    ogma.layouts.forceLink({
      // layout parameters
      autoStop: false,
      iterationsPerRender: 1,
      startingIterations: 10,
      slowDown: 4,
      // allow continuous updates
      continuous: true
    });

    // Simulate a manual stop from the user.
    setTimeout(() => {
      ogma.layouts.stop();
      ogma.view.locateGraph({ duration: 500 });
    }, 5000);
  });
