So what library do you use for hierarchical layouts?

Can anyone recommend a resource for learning how to diagram? Notably, I don't want to free-design directional relationships that are counter intuitive to what people expect. Eg, if Service A calls Service B, does the arrow go to Service B? What about the response? I imagine there are a ton of little questions like this and I'd like to learn to write what people expect to see.

I’d actually start with Tufte: https://www.edwardtufte.com/tufte/books_vdqi

There are standards like UML, but I’ve never found those to be as useful to start with. It’s best to treat this as a “design problem”: first, answer the question: “what am I communicating”.

Then, maybe look into conventions - but often you’ll find less need for one “master UML diagram” and instead use many, smaller diagrams embedded within reference docs.

I feel like project reactor did a good job here: https://projectreactor.io/docs/core/release/api/reactor/core...

Personally I’d like to see more related to inheritance, but I’ll take what I can get. The tooling can be a pain to embed automatic diagrams in

Earlier quoted context omitted.

I don't want to diminish importance of graphviz, but PlantUML is better suited for visualizing state machines, message sequence diagrams and whatnot.

PlantUML is a good syntax. Under the hood... it renders via GraphViz

which is exactly why it's great! :)

As much as I like Graphviz (and I've been using it for ages) I keep looking for an equivalent with two features: - Nicer, more modern looks (the original is too... LaTeX-y for my tastes) - A different layout engine that uses straight arrows and 90 degree turns So far I haven't been able to find any good replacements, although a few JS libraries come reasonably close.

Better integration with TeX, I want to put formulas inside the graph using the exact same fonts as in the rest of my paper.

I used graphviz as the main visualisation for bear-note-graph [1], and it's super-easy to use programmmatically, and gives decent-looking results even for large graphs. It is also pretty customizable. I have a WIP version now using D3, and that one has been harder to manage (when the graph is too large you don't want to have it animate the layout on the fly). If you are curious, I used the same D3 code I have in the…

Curious what you think about something, since it seems like you've been iterating on the challenge of a big interactive graph lately. I've been pondering building a big interactive chart, like a decision tree or differential diagnosis chart, that maps goals/needs/problems to docs/examples/tools (for the Nix/NixOS/Nixpkgs ecosystem, but the basic concept applies to any sprawling ecosystem where discovery is hard). I r…

I didn't check mermaid for bng, but had checked it before (I like visual representations of knowledge, no matter what they are for). Although I found it interesting, my gut feeling here was that if my problem's solution (at that point it was just out of curiosity) was going to be JS-based at some point, I should go directly for D3 (I already had experience, but not recent, with D3).

Mermaid uses D3 under the scenes, so depending on your specifics it could be the best solution anyway, though. Performance wise, I'd expect it to be OK (D3 is pretty fast in most cases) although if there are any issues down the road, fixing them from such a high level library as mermaid could be daunting (it's "easier" to move down from D3 to paper.js or g.js or any other high performance canvas renderer if the case arises).

I'm curious to know which libraries you use.

Also, in my own experience, I was able to get hierarchical layouts Graphviz by using directional graphs with subgraphs.
