Hierarchy Diagram Output Control
Yes you can control the shape of a HID (Hierarchy Diagram). In the hid properties you can control the shape and data shown in your HID.
The cross reference links between each item control the connections shown on the HID. The whole HID layout can be Vertical or Horizontal. The number of levels shown when first rendered (rather than dynamic click and expand) can be controlled. Whether an item is shown more than once if it has multiple cross references and general layout parameters. These are further detailed in How to Set Hierarchy Diagram Properties. Once you are happy with the layout it can be saved for use next time you need a similar pattern.
Your data may produce a short wide tree or a long narrow tree. This can be difficult to see on the screen. This video shows how changing the pivot point, (the node at which the orientation changes from listing horizontally to vertically) can alter the overall display to be more usable.
