I'm working on something in between a BI tool and a SQL IDE. It's definitely code-heavy on the user at the moment compared to a BI tool but an improvement on switching between Python scripts, Postman, a SQL GUI and Excel.

Hey! Thank You for creating datastation.

Are there some videos that walk a user through setting it up to using it?

There are primarily a bunch of tutorials for getting started [0] (these are up to date) and some old videos (not up to date) [1].

I've had bad experiences with superset (though it may have been misconfigured).

On the other hand, Redash has served my startup really well for the first 3 years (and now we're finally moving to Tableau)

In spirit, but with no UI, vega js, they follow the same “grammar of graphics” idea from the same research. Altair does vega charting but in Python. Kibana is using vega in more UI fashion but I haven’t tested it. I think someone should put a proper web ui on top of vega…

I really like the visualization language idea.

I have used Vega + Jupyter a few times. As well as the Vega Viewer extension for VS Code. I haven't used it enough to be proficient and fast, but I have used it enough to know that I want to be.
