Building with KeyLines

Build high performance graph visualization tools quickly

How does KeyLines work?

KeyLines is a JavaScript software development kit (SDK). You can use the technology to quickly build network visualization web components to embed in your applications.

These components use WebGL and HTML5 Canvas for fast performance, and harness a powerful event model and API of functionality to help make sense of data connections.

With detailed API documentation to help you, and a team of KeyLines developers providing support, it’s easy for you to build the custom visualization applications your users want.

//     Sample Code - Exploring graph data in the time bar.

window.onload = async () => {
  KeyLines.promisify();
  const [chart, timebar] = await KeyLines.create([
    { container: 'kl', type: 'chart' },
    { container: 'tl', type: 'timebar' }
  ]);

  // load data into both the time bar and the chart 
  timebar.load(data);
  timebar.zoom('fit');

  chart.load(data);
  chart.layout();

  // When the time bar range changes
  timebar.on('change', async () => {
    // filter the chart to show only items in the new range
    await chart.filter(timebar.inRange);
    // and then adjust the chart's layout
    chart.layout(‘organic’, {mode: ‘adaptive’});
  });
