(I designed and built the Column Explorer feature)

Observable's column summary feature is very nice! But I do think there's a very common lineage around these kinds of diagnostics which motivated both Observables and ours. See Jeff Heer's profiler paper[1] for more.

I'm very passionate about this area because I think "first mile problems" are underserved by most tools, but they take the longest to work out.

We had to do some gnarly things[2] to make this feature work well; and there's a lot of room to make it scale nicely and cover all DuckDB data types.

Interesting, I guess there's plenty of ideas to grab from their work too! https://observablehq.com/documentation/cells/data-table

Personally, thank you for this awesome work!

I find the ease and intuitiveness of navigating it as well as the clarity of the information presented even for the density of a small window or many columns outstandingly pleasant.

Kudos to you!
