Any graph can be sent to the powerful graph layout tool Graph IDE (a separate application) where it can be altered in fine detail. Click the Export tool, diagrammed in the figure below, to do so.
Note: The Export tool is only available in the Manufacturer Edition of the Graph application and requires the separate Graph IDE application (see: Download).
Once in Graph IDE, see its manual (also available at: Graph IDE User Manual) for further information. Graph IDE is very powerful and flexible and, unlike the Graph application, takes some experience to use well.
