Also, in order for them to capture appropriate granularities of detail, they take a lot of time and conversation with readers. I usually go with as little graphs as possible and prefer to write text; it can capture more, better, faster, and be more iterable. For specific areas like state machines or packet sequences I will drill into graphical representations more but otherwise... eh. Text wins.
