This editable organizational chart sample color-codes the Nodes according to the tree level in the hierarchy.
</p>
<p>
Double click on a node in order to add a person or the diagram background to add a new boss. Double clicking the diagram uses the <a>ClickCreatingTool</a>
with a custom <a>ClickCreatingTool.insertPart</a> to scroll to the new node and start editing the <a>TextBlock</a> for its name .
</p>
<p>
Drag a node onto another in order to change relationships.
You can also draw a link from a node's background to other nodes that have no "boss". Links can also be relinked to change relationships.
Right-click or tap-hold a Node to bring up a context menu which allows you to:
<ul>
<li>Vacate Position - remove the information specfic to the current person in that role</li>
<li>Remove Role - removes the role entirely and reparents any children</li>
<li>Remove Department - removes the role and the whole subtree</li>
</ul>
Deleting a Node or Link will orphan the child Nodes and generate a new tree. A custom SelectionDeleting <a>DiagramEvent</a> listener will clear out the boss info
when the parent is removed.
</p>
<p>
Select a node to edit/update node data values. This sample uses the <a href="../extensions/dataInspector.html">Data Inspector</a> extension to display and modify Part data.
</p>

</p>
<p>
If you want to have some "assistant" nodes on the side, above the regular reports,
see the <a href="orgChartAssistants.html">Org Chart Assistants</a> sample, which is a copy of this sample
that uses a custom <a>TreeLayout</a> to position "assistants" that way.
