D3: Simple javascript class wrapper for Hierarchical Edge Bundling Visualization

This is a simple javascript class wrapper (in both css and js) for the Hierarchical Edge Bundling Visualization at http://bl.ocks.org/mbostock/1044242, The interface separates json data, html element, and the actual HierarchicalEdgeBundling class. It is modified so that it will be easier for a web developer to easily add a hierarchical edge bundling 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 HierarchicalEdgeBundling chart:

<script src="lib/d3.min.js" type="text/javascript"></script>
<script src="lib/packages.js" type="text/javascript"></script>
<script src="lib/hierarchical-edge-bundling.js" type="text/javascript"></script>

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

function plotHierarchicalEdgeBundling()
{
 d3.json("readme-flare-imports.json", function(data) {
  var plot = new HierarchicalEdgeBundling("chtHierarchicalEdgeBundling", "infoHierarchicalEdgeBundling", data);
 });
}
</script>
<style>
