May I ask about the official and unoffical(?) ways of interactivity in browser (or elsewhere)? Is there some nice goto material on that?

#142Both VSCode and IntelliJ have PlantUML plugins which can handle DOT code and render it in the IDE. Nice to have. (VSCode's is way smoother though.)

I remember this issue being raised, I think on the graphviz Discourse, and the graphviz developers responding to it as if it was a hard to solve limitation of graphviz for some reason. But I can't for the life of me remember the details.
"Very poor" seems harsh, but, yes, it hurts us, too. (That, and text with slightly-off baselines.) The relevant code starts around https://gitlab.com/graphviz/graphviz/-/blob/main/lib/common/... If this isn't right, maybe somebody can figure out why. Perhaps the loop stops sometimes on the wrong side of the boundary? Anyway, it's equally possible that when the endpoint coord is handed off to a lower level driver, the…
I think I found at some point that the arrows could be made correct -- at least for the SVG rendering in Firefox -- by removing the stroke (stroke-width="0").

#144Here are some cool things I've done recently with graphviz: 1. Draw "sketch" style graphs using https://sketchviz.com/new 2. Draw graphs of memory usage in golang programs (using pprof): https://graphviz.org/Gallery/directed/pprof.html 3. Embed graphviz into Sphinx docs (shameless self-promotion: https://docs.robusta.dev/master/catalog/triggers/index.html#... )
I like the output of Sketchviz. Do yo know if it is possible do make such output directly from desktop app?
Haven't tried it yet, but this looks pretty spot on: https://github.com/gpotter2/sketchviz

My single biggest issue with Graphic is that the quality of Arrow end-points is very poor. They don't terminate cleanly at the destination. This is visible in the 2nd link you've posted. I'm amazed that this hasn't been addressed. It's been there for years. Makes the end products impracticable for distribution in a professional setting. It's Ok if you're the only consumer ... not great for other cases.
I never had this problem. Arrow style is configurable if I remember correctly. You can configure (extend) also overlapping in boxes so the arrows never enter into the box area.
I'm talking by heart and I could be wrong in any case.

#146The `gvpr` tool in graphviz deserves more recognition. Graphviz, at its core, is a simple graph description language (DOT), which allows progressive enhancement , and a bunch of auto-layout tools where some double as renderers. The double-duty of the layout/renderers masks GraphViz's true power, which is that you can create a pipeline modifying your graph source (confusingly referred to as '.dot' files), progressivel…
I'm actually disappointed that `gvpr` isn't mentioned at all on GraphViz's main page, because I think it's its most powerful tool. All I could find are manpages, and not even on GraphViz's own website! https://manpages.debian.org/testing/graphviz/gvpr.1.en.html
Never had heard about it and use graphviz since... dunno, more than 15 years probably.
Re: Graphviz: Open-source graph visualization software
#147I've used GraphViz a number of times and highly recommend it as a standard tool on your belt. Having a stand-alone executable that can export to SVG is great. The most complex thing I've done with it [1]: a tool (MIT-license) that builds diagrams of the data and addressing pipeline for a DSP processor, and lets one 'scrub through' the assembler code frame by frame and see the values propagate through the blocks. Also…
You can use invisible clusters also to group things
Re: Graphviz: Open-source graph visualization software
#148Earlier quoted context omitted.
My graphviz-fu got so much better when I started using invisible objects for the grid-like layouts. At that point you're just using graphviz for positioning/spacing/styling instead of creating the overall topology.
This sounds interesting, can you expand on that a bit please?
if you want X nodes falling near in the graph you just put them into a box with white lines and they move as one from this point. Can be made with the cluster environment.

How come the graph edges are "--" and the digraph edges are "->", but not "That means it's not possible to flip graph/digraph to see how it looks with/without arrows, but naievely it doesn't seem that the difference makes any difference except making that difficult, if the connections must always be written left to right. (I've not used more advanced features, so it could be that it does more, or could be that it was built expecting people to know what they want first, which would all be fine)
