Does the official Mermaid library still require a full or headless browser environment in order to lay out the SVG? If so, Pele is great news for embedding Mermaid rendering in other places.

Is pele open source? I tried to find the source code of it but I was unable in finding so Edit: found it, https://github.com/obsidianmd/pele Also folks, this is a good reminder to please have a github icon on the top of the page to easily show git/github links if the app is open source, also helps in the fact that I can star your projects and bookmark them more easily :-D

Just FYI, "pele" is "mouse" in Latvian. :)

Anytime I try mermaid for anything more complex than a toy diagram I always end up absolutely frustrated by the arcane and topologically poor layout that is produced. Styling seems like a trivial problem by comparison.

Tools like this are so amazing because they allow Claude to edit and draw and save to a single markdown file. So practical! Version control friendly. People can use them, sure. Buy AI can really take off with tools like this.

Noting that the mermaid preview in the playground is broken.

The examples are not very dark-mode friendly

> A flowchart subgraph keeps its own direction even when it links to nodes outside the subgraph. This, in and of itself, is sufficient reason for me to switch, even if it were slower than Mermaid.js. I’ve not even made it through the list yet and I’m sold.

Brazilian me thought it was an homage to Pelé. I’m glad the text explains the name.
