Laying out the diagram
The view you get after adding the missing graphical representations might
not be ideal. Therefore, the Layout Entire Diagram option might be useful.
It will expand your diagram and adjust the drawing area accordingly.
To layout the diagram, right-click inside the diagram window and select the Layout
Entire Diagram in the pop-up menu.
Note: The Layout diagram feature can be used on the entire diagram or on a
selection of objects.
