I'm a fan of dimple as well. I created custom tags for it[1] so you can draw charts in the following manner:

  <dimple-chart data="data" height="300" width="300" margin-bottom="15%" type="bar">
    <dimple-axis position="y" type="measure" field="Awesomeness"></dimple-axis>
    <dimple-axis position="x" type="category" field="Word" orderBy="Word"></dimple-axis>
    <dimple-legend x="10" y="10" width="500" height="30" ></dimple-legend>
  </dimple-chart>

I just started building this using Mozilla's x-tags. Mainly to clean up my own app, others are welcome to take a look.
