I really bloody hate to draw network diagrams manually. Aren't there tools which could let me describe the network in a structured textual format and get a nice picture rendered?
It renders basic pictures by default, but is very configurable - see the gallery, or Google Image search for examples - but not easily configurable beyond coloured lines, dotted lines and shapes. You can get "tidy" pictures with a bit of effort. "Nice" is more debatable.
Sadly, it is the product of decades of time, academia and open source; and by that I mean very effective, feature filled and capable, but also ugly, opinionated, and gratingly temperamental.
I used to know of a website which would render GraphViz diagrams as you type them, but I haven't been able to find it recently. Anyone know it?
