    Change the Layout of a Network Diagram
    public void DiagramElementQueryResultAndNetworkDiagramSubsetClasses(Geodatabase geodatabase, DiagramManager diagramManager, string diagramName)
    {
      // Retrieve a diagram
      using (NetworkDiagram diagramTest = diagramManager.GetNetworkDiagram(diagramName))
      {
        // Create a DiagramElementQueryByElementTypes query object to get the diagram elements we want to work with
        DiagramElementQueryByElementTypes query = new DiagramElementQueryByElementTypes();
        query.QueryDiagramJunctionElement = true;
        query.QueryDiagramEdgeElement = true;
        query.QueryDiagramContainerElement = true;
    
        // Retrieve those diagram elements
        DiagramElementQueryResult elements = diagramTest.QueryDiagramElements(query);
    
        // Create a NetworkDiagramSubset object to edit this set of diagram elements
        NetworkDiagramSubset subset = new NetworkDiagramSubset();
        subset.DiagramJunctionElements = elements.DiagramJunctionElements;
        subset.DiagramEdgeElements = elements.DiagramEdgeElements;
        subset.DiagramContainerElements = elements.DiagramContainerElements;
    
        // Edit the shapes of the diagram elements - left as an exercise for the student
        TranslateDiagramElements(subset);
    
        // Save the new layout of the diagram elements
        diagramTest.SaveLayout(subset, true);
