Vis.js 是一个动态的基于浏览器的可视化库，特点是易用，可处理大量的动态数据，并与这些数据进行交互操作。该库包含 DataSet, Timeline,

示例代码：
<!doctype html> <html> <head> <title>Timeline | Basic demo</title> <script src="http://visjs.org/dist/vis.js"></script> <link href="http://visjs.org/dist/vis.css" rel="stylesheet" type="text/css" /> <style type="text/css"> body, html { font-family: sans-serif; } </style> </head> <body> <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); </script> </body> </html>
