Thank you. I'm using Angular, but no library beyond that. I was looking for a library for the diagram, but didn't find anything that suited my needs, so it is just custom code. I would like to find a library which could draw nicer arrows at least, since the diagram currently gets pretty confusing when there are many connections.

I know what you mean about libraries. There are so many out there that cover 80% of my use case, but they're all missing 20% in different areas.

I think I've finally found what I'm looking for in Raphael.js + Raphael.FreeTransform though.
