Show HN: Interactive SQL Tutorial with a visual query builder

https://seaquel.app/learn-sql is an interactive SQL tutorial with a visual query builder.

JOINs, CTEs, subqueries can be difficult to understand. With the visual builder and SQL editor side-by-side, I hope these concepts are easier to understand.

FWIW, the tutorial is part of Seaquel, the SQL client I've always wished I had. I showed that to HN a few weeks ago.

Curious to hear what you think of the tutorial.

Thanks
