First of all, nice to meet you! The honest answer is timing: the first VISUALIZE commit on my side was april 25th; ggsql-duckdb's first commit was April 23rd. So I genuinely didn't know it existed!

About the name: yours is the official Posit one, and you were there first, so I'll rename my branding; there should be one ggsql, and it's yours. Mine only exposes VISUALIZE as the keyword anyway.

The actual name of the extension is the-stats-duck, which runs inside duckdb-wasm (it powers an in-browser data tool) and emits a Vega-Lite spec inline for the host to render. Your implementation (which I think is Rust based and an in-process HTTP server that opens a browser), is a native pattern, but correct me if I'm wrong! mine is deliberately thin and wasm-safe, not a whole engine.

About the parity, you're right, and I'm not chasing it; for real grammar-of-graphics, ggsql should be the tool! but, if that's ok with you, I'd love to keep the syntax aligned!

No objections at all. But probably good to describe that it is ggsql-inspired rather than a full reimplementation as it could lead to user confusion about what syntax is supported etc

And you are correct about how our extension is implemented and it isn’t currently wasm ready
