本示例向当前演示文稿的第一张幻灯片中添加一个棱锥图。
Sub CreatePyramidDiagram()
    Dim dgnNode As DiagramNode
    Dim shpDiagram As Shape
    Dim intCount As Integer
    'Add pyramid diagram to current document
    Set shpDiagram = ActivePresentation.Slides(1).Shapes _
        .AddDiagram(Type:=msoDiagramPyramid, Left:=10, _
        Top:=15, Width:=400, Height:=475)
    'Add first diagram node child
    Set dgnNode = shpDiagram.DiagramNode.Children.AddNode
    'Add three more diagram child nodes
    For intCount = 1 To 3
        dgnNode.AddNode
    Next intCount
