title: d3js Zoomable Icicle data
body: <p>I want to modify the <a href="http://bl.ocks.org/1005873" rel="nofollow" title="zoomable icicle">zoomable icicle</a> plot of d3js to include my own data.  However, I cannot find the "readme.json" file to modify the data, nor does the graph render locally.  Where can I find this file, or if I create my own json file, how should the data be formatted?</p>
