I've been working on https://github.com/btucker/selkie which is a complete implementation of the Mermaid parser & renderer in rust as an experiment in what's possible with Claude Code. It's still rough around the edges, but I've been blown away by what's been possible. (I'm now using it as a test repo for https://github.com/btucker/midtown)
Playground here: https://btucker.github.io/selkie/
One of the cool features is it can use kitty to output diagrams direct to the terminal (if kitty is supported like in ghostty).
I'm planning to blog about the whole process soon.
