Mermaid.js is incredibly cool

As mentioned [earlier](https://blog.themillhousegroup.com/2023/10/markdown-and-mermaid-on-blogger-in-2023.html) I'm now able to embed [Mermaid.js](https://mermaid.js.org/) diagrams directly into this blog and I'm going to just post *exclusively* about just how great Mermaid is. If you've __ever__ drawn a technical diagram in __anything__ from MS Paint through [Draw.io](https://www.drawio.com/) and even [Excalidraw](https://excalidraw.com/) and then had to convert the diagram into a PNG or JPEG in order to embed it into a document, knowing full-well that the slightest change is going to involve re-doing a significant chunk of that work, **get Mermaid into your life right now**. ### Mmmm Pie I mean, look at this: ```mermaid pie title Pets adopted by volunteers "Dogs" : 386 "Cats" : 85 "Rats" : 15 ``` That's *four* lines of simple text: ``` pie title Pets adopted by volunteers "Dogs" : 386 "Cats" : 85 "Rats" : 15 ``` ### Flowcharts with flair ```mermaid flowchart TD subgraph First Approach A[Start] --> B{Does it work?} B -->|Yes| C[OK] B --->|No| D[Rethink] end subgraph Second Approach F[Start] --> G{Does it work?} G -->|Yes| H[OK] G -->|No| J[Oh dear] end D --> F ``` Is just: ``` flowchart TD subgraph First Approach A[Start] -- > B{Does it work?} B -->|Yes| C[OK] B --->|No| D[Rethink] end subgraph Second Approach F[Start] --> G{Does it work?} G -->|Yes| H[OK] G -->|No| J[Oh dear] end D --> F ``` I really like how easy it is to declare those `subgraph` elements for visual grouping. And did you notice how a different length "arrow" hints to Mermaid to render a longer arc? Delicious. Expect to see a lot more diagrams like these around here in the future!
