title: neo4j Grass documentation? Trying to set node size from a property
body: <p>Is this possible using .grass?
  I made a property called diameter and set it to "50px" on a node, but it doesn't work. The nodes just disappear. </p>
  
  <pre><code>"node.User": {
      "color": "#FB95AF",
      "border-color": "#E0849B",
      "text-color-internal": "#FFFFFF",
      "caption": "{name}",
      "diameter": "{diameter}"
    }
  </code></pre>
