But isn't this then just another tool that you're including in your project? I don't get why I would want to add this as a visualization tool to a project, if it's already using R, or Python, etc...

I mean, is it to avoid loading the full data into a dataframe/table in memory?

I just don't see what the pain point this solves is. ggplot solves quite a lot of this already, so I don't doubt that the authors know the domain well. I just don't see the why this.

Well there's always going to be a dependency anyway: loading the data, making it a dataframe, visualizing it, this might be 3 libraries already.

In a sense I really get your complaint. It's the xkcd standard thing all over, we now have a new competing standard.

I think for me it's not so much the ggplot connection, or the fact that I won't need a dataframe library.

It's that this might be the first piece of a standard way of plotting: no matter which backend (matplotlib, vega, ggplot), no matter how you are getting your data (dataframes, database), where you're doing this (Jupyter or marimo notebook, python script, R, heck lokkerstudio?). You could have just one way of defining a plot. That's something I've genuinely dreamt about.

And what makes this different from yet another library api to me is that it's integrated within SQL. SQL has already won the query standardisation battle, so this is a very promising idea for the visualization standardisation.

    I see, that's insightful. At first sight I thought of it as a kind of novelty, extending SQL with a visual grammar to integrate with a specific plotting library. But from your comments I can now imagine it has potential as a general solution for that space between data - wherever it comes from, it can typically be queried by SQL - and its visualization.

    Thinking further, though, there might be value in extracting the specs of this "grammar of graphics" from SQL syntax and generalized, so other languages can implement the same interface.
