I stumbled across Mermaid when I saw @ronaldwidha retweeted a tweet about it. Mermaid is a library for writing diagrams instead of draw them similar to Marked to markdown, awesome! So, I thought I could use this in my blog just in case I need to draw some flowcharts or sequence diagrams in the future. DocPad uses Marked to render markdown to html via docpad-plugin-marked but natively, it doesn’t support Mermaid syntax.
