(Big fan of graphviz, it was such a shame when AT&T pulled funding!)

Maybe helpful, more for visual graph data analysis than say arch diagramming: we build Graphistry specifically for interactively analyzing more data than these tools, eg, GPU client + GPU server, and being more batteries-included. The free Graphistry Hub site is similar to diagrams.net and GitHub for folks who aren't self-hosting GPUs.

We are still working towards OSS'ing the core renderer, but all our new graph neural networks + graph compute + graph layout layers are all already OSS-first (see PyGraphistry), and we are part of the apache arrow + rapids communities. If your kind of thing, we are very much hiring :)
