1. Yeah.

2. Strong disagree. IMHO icons in diagramming are obsolete for most purposes (smacking of UML and over-wrought database diagrams) and are likely to lead to confusion for the majority of viewers who - at best - aren't quite sure what you exactly mean in this particular case.

3. Which is what graphviz is for. It literally draws itself. Subgraphs are the groupings.

4. I would instead suggest modifying an existing graphviz .dot file, or man dot.

Re: 2 I would like a large icon and small text that confirms my intuition about what the icon means. The icon thereby eventually becomes part of my lexicon.

I don’t even see the text, I just see database, load balancer, Redis cache…
