expression.Root
expression Required. An expression that returns a DiagramNode object.
Example
The following example creates an organization chart and adds child nodes to the root diagram node.
Sub Root()
Dim shpDiagram As Shape
Dim dgnRoot As DiagramNode
Dim intCount As Integer
'Add organization chart to the current document
Set shpDiagram = ThisDocument.Shapes.AddDiagram _
(Type:=msoDiagramOrgChart, Left:=10, _
Top:=15, Width:=400, Height:=475)
'Add the first node to the diagram
shpDiagram.DiagramNode.Children.AddNode
'Assign the root diagram node to a variable
Set dgnRoot = shpDiagram.DiagramNode.Root
'Add three child nodes to the root node
For intCount = 1 To 3
dgnRoot.Children.AddNode
Next intCount
End Sub
