One feature I would love to see a declarative diagramming solution would support is a hover pop-up with more information or nested diagrams.

There's also mermaidjs to excalidraw https://github.com/excalidraw/mermaid-to-excalidraw

Project's Cargo.toml file says code is licensed under MIT license, but there's no license file in the repository, so Github doesn't show what the project is licensed under. Please add the license file so that people see it without having to dig through the code/configuration to determine that.

Being able to express a workflow or diagram and then have AI implement would be awesome to have a tight loop.

I use PlantUML for most diagramming but for anything with more than about 5 components in it I'm spending 20-30% of my time desperately trying to tweak the layout with hints.

It's an interesting approach to embed comments and then build that into the layout engine. I've always thought it would solve a lot of my issues if I could just lock the coordinates for certain components and then let the layout engine do the rest with those as hard constraints. This looks like something similar to that approach.

I really want this because the alternative is to spill over to completely manually maintained diagrams using GUI tools which then can't be easily integrated with source control - I want the same commit that changes the code to also change the architecture diagram for that code. Then it is part of code review and integrates to the whole process well.

One thing that's missing from my perspective (and this is probably true for Homebrew packaging as well, but I don't do that) is Git tags / GitHub releases associated with your Cargo releases.

I can work around it for now by using an explicit release (`9ccd9bf53f9a309ccda42b5c17e9c1056493fb90` is what I'm assuming was your 0.1.0 release point).

I've also assumed that npm10 is sufficient (which currently installs node22 on MacPorts).

I don't see a button for it (on mobile currently, and will check thoroughly at my computer) -- is there a button to add a node?

Another feature I've always craved for code diagramming is "collapse downstream nodes" -- though it might be outside of your scope (and mermaids?).

But now I can interactively make changes to the diagram with this, it's very productive.

The lack of this has been a sticking point making us lean to dropping mermaid, so very cool to see!
