D3: Simple javascript class wrapper for Sankey Plot

This is a simple javascript class wrapper (in both css and js) for the Sankey Plot Visualization at http://bl.ocks.org/billierinaldi/raw/3779574/, The interface separates json data, html element, and the actual SankeyPlot class. It is modified so that it will be easier for a web developer to easily add a bipartite chart into their application.

Below is the link to the source code (remember to put in in the web folder of a web server such as xamp so that the html page will be able to download the json in the same folder):

Below is the html which includes the javascript that download a json data and then display as a SankeyPlot chart:

<html>
<head>
<link href="lib/sankey-plot.css" rel="stylesheet"></link>

<script src="lib/jquery-2.1.3.min.js" type="text/javascript"></script>
<script src="lib/d3.min.js" type="text/javascript"></script>
<script src="lib/sankey.js" type="text/javascript"></script>
<script src="lib/sankey-plot.js" type="text/javascript"></script>

<script>
$(function(){
 plotSankey();
});

function plotSankey()
{
 d3.json("energy.json", function(energy) {
  var plot = new SankeyPlot("chtSankey", energy);
 });
}
</script>
<style>
body{
padding-top: 10px;
}
</style>
</head>
<body>
<div id="chtSankey" class="sankeyplot" ></div>  
</body>
</html>
