<p>
This sample demonstrates a data flow or workflow graph with labeled ports on nodes. These ports are set up as panels, created within
the <b>makePort</b> function. This function sets various properties of the <a>Shape</a> and
<a>TextBlock</a> that make up the panel, and properties of the panel itself. Most notable are
<a>GraphObject.portId</a> to declare the shape as a port, and <a>GraphObject.fromLinkable</a> and
<a>GraphObject.toLinkable</a> to set the way the ports can be linked.
</p>
<p>
The diagram also uses the <b>makeTemplate</b> function to create the node templates with shared features.
This function takes a type, an image, a background color, and arrays of ports to create the node
to be added to the <a>Diagram.nodeTemplateMap</a>.
</p>

For the same data model rendered somewhat differently, see the <a href="dataFlow.html">Data Flow (horizontal)</a> sample.
