But why be exclusive? Why not "Chart language for computer programs to generate"?
I don't want to use an agent at all, but i wouldn't mind generating some charts with an easy-to-generate markup language...
Careful, they'll spring something XML-derived on us.
But for that we already have mermaid.js (and its precursor Graphviz/dot).
The only reason to use this instead of existing, mature ones designed for humans is if you are an AI agent.
