+      This sample is a modification of the <a href="../samples/stateChart.html">State Chart</a> sample that makes use of
+      the LinkLabelDraggingTool that is defined in its own file, as <a href="LinkLabelDraggingTool.ts">LinkLabelDraggingTool.ts</a>.
+    </p>
+    <p>
+      Note that after dragging a link label you can move a node connected by that link and the label maintains the same position
+      relative to the link route. That relative position is specified by the <a>GraphObject.segmentOffset</a> property.
+      This sample also saves any changes to that property by means of a TwoWay <a>Binding</a>.
+    </p>
+    <p>
+      See also the similar <a href="LinkLabelOnPathDragging.html" target="_blank">Link Label On Path Dragging sample</a>,
+      where the label is constrained to remain on the path of the link.
