I use PlantUML to create quick network diagrams.

It's the only solution I found which allows tailoring a diagram if it renders poorly.

For example, if access switches are to be on the left, and trunk switches on the right, PlantUML is the only solution I found which adequately allows the user to add such constraints, via:

S1 --E-- S2

Hey, what style of diagram are you using for this? Deployment diagram? Do you have link to an example?

Layout hints in legacy activity diagrams, from memory:

Can take compass coordinates from memory, in shorthand.

In Python, I pull a network topology from an API, then convert it to PlantUML, then edit a few arrows/lines so to point the right way, the entire topology adjusts accordingly, and generally I arrive at a useable diagram very quickly.

Way quicker than Visio, and nothing else seems to be able to do this (e.g. graphviz doesn't allow this).
