title: How to run Mike Bostock's D3 examples?
body: <p>I've been trying to run Mike Bostock's <a href="http://bl.ocks.org/mbostock/6747043" rel="noreferrer">See-Through Globe</a> example, but the references to his json files are incorrect if you try to reproduce it locally.</p>
  <p>The issue comes from this line of code:</p>
  <pre><code>d3.json(&quot;/mbostock/raw/4090846/world-110m.json&quot;, function(error, topo) {
        var land = topojson.feature(topo, topo.objects.land),
            grid = graticule();
  });
  </code></pre>
  <p>I've followed this example:
  <a href="https://stackoverflow.com/questions/19941975/d3-us-states-in-topojson-format-filesize-is-way-too-large">d3: us states in topojson format filesize is way too large</a></p>
  <p>and tried to change the url to these variations to better reference those files for an external user;</p>
  <pre><code>&quot;https://raw.github.com/mbostock/topojson/master/examples/world-110m.json&quot;
  &quot;https://render.github.com/mbostock/topojson/master/examples/world-110m.json&quot;
  &quot;http://bl.ocks.org/mbostock/raw/4090846/world-110m.json&quot;
  </code></pre>
  <p>but I'm never allowed access. Any idea on how to correctly reference the json file?</p>
  <p>I've tried some if his other examples as well, and have run into the same issue every time. Has anyone else had any success reproducing the examples?</p>
