<p>
This sample demonstrates reading JSON data describing the relative rankings of NFL teams
during the 2015 season and generating a diagram from that data.
The ranking information came from beatgraphs.com.
</p>
<p>
The JSON data is basically just a list of relationships.
Unlike most model data, there are no elements describing the nodes --
the node definitions are implicit in the references from the links.
Hence the <a>Diagram.model</a> has <a>GraphLinksModel.archetypeNodeData</a> set to a JavaScript object.
</p>
<p>
The node template uses the <b>convertKeyImage</b> function to convert the team name
into a URI referring to an image on our web site.
