body: <p>What's the best way to load a custom JSON file as data into an A-frame component ? For example, the JSON file may contain coordinates of points. I want to load the file as an asset and use the parsed json object in the component.</p>
  
  <pre><code>{"coordinates": [{"x": 0, "y": 1, "z": 2}, // ...]}
  </code></pre>
