Org Chart Control/Plug-In for VB.NET WPF multitouch application

I have been working on a UI app (written in VB.NET and using WPF) which creates charts using the Microsoft Chart Control fo开发者_如何学运维r Windows Forms. The application retrieves data periodically from a remote database, parses and formats the data to create series, and then creates a chart based off the series which is then hosted in a WindowsFormsHost control. So far this process has been working well.

I have now been tasked with adding an organizational chart. The requirements state that it should have "drill-down" and touch functionality. I have not been able to find an org control like the chart controls I have been using. The closest one I found was the tree view control that comes with .NET Studio. I have looked at the WPF: Org Chart TreeView Conditional Formatting SO question, and also read the recommended Josh Smith CodeProject articles, but my boss does not want me to pursue developing my own org control at this time.

Is there a good third-party solution/plug-in already available? It would need:

• ...to be capable of being integrated into the WPF as a control (like the Chart Control mentioned above),
• ...to generate org charts dynamically by connecting to a remote Oracle Database to retrieve the data based on either predefined views or specific select statements (or read a flat file to generate an XML file containing all the relationships and branches),
• ...to have a hierarchy that was navigable by touch, i.e. touching a node would show the branches beneath that node--touching the node again would hide the branches.

Any suggestions/help are greatly appreciated. I haven't been able to find any third-party options that fit all these requirements.
