+    <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.ts">SerpentineLayout.ts</a>.
+    </p>
+    <p>
+      It also has <a>Layout.isViewportSized</a> set to true, so that resizing the Diagram DIV will automatically re-layout.
+    </p>
