Really cool project! Would love to see a standard established for representing visualizations in SQL!
I built a whole dashboarding tool on top of the idea:

But Shaper takes a more pragmatic approach and just uses built in functionality to describe how to visualize the results.
The most value I see with viz as SQL is that it's a great format for LLMs to specify what they want while making it easy to audit and reproduce.
Just built a slack bot on top of that concept last week:
