a visual interaction system

Vis.js is a dynamic, browser based visualization library. The library is designed to be easy to use, to handle large amounts of dynamic data, and to enable manipulation of and interaction with the data. The library consists of the components DataSet, Timeline, and Graph.

The vis.js library is developed by Almende B.V, as part of the CHAP.

A basic example demonstrating how to use the vis.js timeline is shown below. See the gallery below for more examples.

<!doctype html>
  <title>Timeline | Basic demo</title>
  <script src=""></script>
  <link href="" rel="stylesheet" type="text/css" />

  <style type="text/css">
    body, html {
      font-family: sans-serif;
<div id="mytimeline"></div>

<script type="text/javascript">
  var container = document.getElementById('mytimeline');
  var data = [
    {id: 1, content: 'item 1', start: '2013-04-20'},
    {id: 2, content: 'item 2', start: '2013-04-14'},
    {id: 3, content: 'item 3', start: '2013-04-18'},
    {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-04-19'},
    {id: 5, content: 'item 5', start: '2013-04-25'},
    {id: 6, content: 'item 6', start: '2013-04-27'}
  var options = {};
  var timeline = new vis.Timeline(container, data, options);
