Hello Astro is a multi purpose Astro starter theme written in Typescript, TailwindCSS and AlpineJS. It supports Markdown and MDX based pages and blog posts.
My apologies, it looks like Mermaid v9 no longer loads from CDN. I've fixed it by loading the latest version of Mermaid. Hopefully if you sync the codebase, it will work for you as well.
Visit https://hellotham.github.io/hello-astro/blog/2022-08-20-mermaid-diagrams/ and looks like Mermaid Diagrams are broken.
I'm use MS Edge v119.0.2151.72
