The second part of the application programs and the corresponding code modules mentioned above may be executed to implement one or more graphical user interfaces (GUIs) to be rendered or otherwise represented upon the display 614. Through manipulation of the keyboard 602 and the mouse 603, a user of the computer system 600 and the application may manipulate the interface to provide controlling commands and/or input to the applications associated with the GUI(s).

The method of displaying large diagrams may alternatively be implemented in dedicated hardware such as one or more integrated circuits performing the functions or sub functions of one or more of the steps shown in FIG. 5. Such dedicated hardware may include graphic processors, digital signal processors, or one or more microprocessors and associated memories.

The foregoing describes only some embodiments of the present invention, and modifications and/or changes can be made thereto without departing from the scope and spirit of the invention, the embodiments being illustrative and not restrictive.
