+  <div id="sample">
+    <div id="myDiagramDiv" style="background-color: whitesmoke; border: solid 1px black; width: 100%; height: 600px"></div>
+    <p>
+      This sample demonstrates a custom Tool, LinkLabelOnPathDraggingTool, that allows the user to drag the label of a Link, but
+      that keeps the label exactly on the path of the link. The tool is defined at <a href="LinkLabelOnPathDraggingTool.ts">LinkLabelOnPathDraggingTool.ts</a>.
+    </p>
+    <p>
+      The label on the link can be any arbitrarily complex object.
+      It is positioned by the <a>GraphObject.segmentIndex</a> and <a>GraphObject.segmentFraction</a> properties.
+      The segmentIndex is set to NaN such that the whole link path acts as the segment, and the segmentFraction is set by the LinkLabelOnPathDraggingTool.
+      A two-way data binding on segmentFraction automatically remembers any modified value on the link data object in the model.
+    </p>
+    <p>
+      The tool is derived from a similar tool, <a href="LinkLabelDraggingTool.ts">LinkLabelDraggingTool.ts</a>, that allows
+      the user to drag the label in any direction from the mid-point of the Link path.
+    </p>
