A fast interactive 3D alternative for visualizing large graphs is Graphia: https://github.com/graphia-app/graphia https://graphia.app However, it's currently suffering from the Qt switch from 5 to 6.

Regarding Graphviz itself, I wonder why is there no special layout logic for planar graphs? They can be recognized and embedded on the plane in linear time without intersecting edges, so it would be very nice if some of the Graphviz tools actually did that.

A recent set of minimal graph coloring Graphviz visualizations of mine: https://gitlab.com/nsajko/example_optimally_colored_graphs

Earlier quoted context omitted.

Sketchviz look great. Is there an option to export vector graphics (for example svg)?

If you hold down control, the "Download PNG" button becomes "Download SVG". Super intuitive, I know! :)

Haha, why is that feature hidden? Like the latest Tesla Model 3 v11 update hides many features :-)

I've never been that happy with the output from any of the different graphviz engines. I'd like to see a UI graph editing tool which can import and export .dot format, but also allows manually moving nodes (which I guess wouldn't get exported unless arbitrary metadata is supported), and ofc exports to svg. Maybe there's already something similar I haven't stumbled across yet?

I guess my use case is mainly swimlanes and places where nodes don't have to have the same rank.

Totally agree with this. I always want to start with graphviz but then modify the output afterwards to fix the layout

Always wanted a way to (have GCC?) send a call graph to graphviz. A reduced version indicating calls across files would also be useful. I get that polymorphism can mess that up, so maybe just link callers to the base class in those cases.

I remember being able to set that up with clang (obviously not indirect calls).
