ForceLink

This example shows the legacy force-link layout algorithm. It is much slower than the new version but can give good results on very small graphs.

index.tsindex.htmlstyles.css

import Ogma from '@linkurious/ogma';

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

ogma.events.on('layoutStart', layout => console.log('Layout started', layout));
ogma.events.on('layoutEnd', layout => console.log('Layout done', layout));

ogma.generate
  .barabasiAlbert({
    nodes: 100,
    m0: 10,
    m: 1
  })
  .then(graph => {
    ogma.setGraph(graph);
    ogma.view.locateGraph();

    ogma.layouts.forceLink().then(() => {
      ogma.view.locateGraph({
        easing: 'linear',
        duration: 300
      });
    });
  });
