initialViewportSpot property
      
      Spot
      get
      initialViewportSpot
      
    
    
Gets or sets the spot in the viewport that should be coincident with the #initialDocumentSpot of the document when the document is first initialized. The default value is Spot.TopLeft.
If you set this, often you will also want to set #initialDocumentSpot. If you set #initialPosition, it will take precedence over this property.
Setting this property and #initialDocumentSpot has the same effect as implementing an "InitialLayoutCompleted" DiagramEvent listener that calls #alignDocument.
Implementation
_i3.Spot get initialViewportSpot => _i4.getProperty(
      this,
      'initialViewportSpot',
    );
      
      set
      initialViewportSpot
      (Spot value) 
      
    
    
    
Implementation
set initialViewportSpot(_i3.Spot value) {
  _i4.setProperty(
    this,
    'initialViewportSpot',
    value,
  );
