<p>
This sample demonstrates a custom Layout, SerpentineLayout, which assumes the graph consists of a chain of nodes.
The layout is defined in its own file, as <a href="SerpentineLayout.js">SerpentineLayout.js</a>.
</p>
<p>
It also has <a>Layout.isViewportSized</a> set to true, so that resizing the Diagram DIV will automatically re-layout.
