The relation to the subject of the thread is Ruby Central. Here's the relation: https://www.mermaidchart.com/play#pako:eNqrVkrOT0lVslJKL0osy...

HN discussionIMO mermaid is awesome, but for two somewhat indirect reasons: - There’s an almost wysiwig editor for mermaid at https://www.mermaidchart.com/play . It’s very convenient and appropriately changes the layout as you draw arrows! - Notion supports inline mermaid charts in code blocks (with preview!) It’s awesome for putting some architecture diagrams in Eng docs.
