I’m a visual thinker, so I usually reach for mind maps and flowcharts when I brainstorm ideas or plan projects. They help me get a full-picture overview of all my thoughts and the nuggets of information I’ve collected. While Notion isn’t a mind-mapping or flowchart tool, I discovered a hidden gem: Mermaid.js. It’s a text-based diagramming tool that works perfectly within Notion’s code blocks. And it turns out to be exactly what I needed — a minimal and fast tool to create flowcharts and mind maps.
