This is more for diagramming small graphs. If you are trying to render large networks, there are better alternatives.

For OSS graph visualization libraries, check out: - Sigma.js - Vis.js

For commercial options: - Ogma (disclosure: my company builds that one) - KeyLines

+1 for Vis.js

I've used it to map wireless trading networks with lots of connections.

The fact that you can make the nodes clickable to other webpages etc is a great feature for building "drill down" views.

You can’t mention commercial options without mentioning yWorks. Their product is absolutely amazing and I’d use it for everything if it wasn’t for the steep cost.

(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 :)

As someone working at yWorks on yFiles, thanks for the kind words :-)

Having used Graphviz extensively over the years as well, the cost of yFiles is certainly unfortunate, but I guess we simply serve a different markt segment than Graphviz or D3. (On a somewhat related note: Our online graph editor, yEd Live, support parsing a subset of Graphviz' syntax and that enables running at least some yFiles layout algorithms on Graphviz graphs. No export back, though.)

Are Sigma and Vis widely-usable (i.e. have C bindings), or only for browsers/JS enginers?

js.cytoscape.org is pretty cool too for fast layout of large nets
