Cerebus asks: "I'm taking over administrative and management functions for a network, and one of the tasks is, of course, providing accurate diagrams for the whole shebang. In playing with various tools for this (Dia, Visio, Kvivio, xfig, tgif, etc). I've noticed that each package has it's own idea about what abstract icon to use for various devices (what Visio would call "logical" icons). While there is some overlap, the meaning attached to an icon is sometimes different between applications, and what's worse is that (using the example of Visio) the same application has multiple different icons for the same type of device! Is there any kind of standard for network diagram iconography? Should there be?"
