asciidoc-diagram & Kroki look cool, hadn’t seen them. I don’t think Plot’s very good at (or built for) that sort of diagramming, though you can do it if you want: https://observablehq.com/@observablehq/plot-finite-state-mac....

What I personally like most about Plot is that it’s purely JavaScript (/ TypeScript); it doesn’t try to be serializable as JSON and portable to Python etc. So whereas Vega-Lite has to have its own expression language (https://vega.github.io/vega/docs/expressions/):

  "transform": {
    "calculate": [{"field": "b2","expr": "2*datum.b"}],
    "filter": "datum.b2 > 60"
  },

…in Plot you’d use plain JavaScript:

  y: d => 2 * d.b,
  filter: d => d.b2 > 60

…which I find easier and more powerful. (But I don’t need VL’s portability; others may.)
