mosaic

I think https://github.com/uwdata/mosaic is really promising here. See the example https://idl.uw.edu/mosaic/examples/linear-regression.html where the user can recalculate a linear regression based on their selection. You'd still need to implement any custom selection widgets, data transformations (like other statistical tests) etc. still missing, but i like the technical design to build on top off. It uses https://github.com/observablehq/plot under the hood, which aims to have just as flexible a grammar as ggplot (already quite capable) but with interactive features (built by the creator of d3 and uses it under its hood).

the uw data lab behind vega also has a new library mosaic[1] that seems pretty exciting. My impression was it allows flexible data transformation/slicing in both the client side and server side, with the same dsl. [1] https://github.com/uwdata/mosaic

Very cool! What about projects/integrations with - duckdb which also supports WASM - UWData's Mosaic (https://github.com/uwdata/mosaic) which supports real-time plots would be really nice to have a kind of "drop-in" page that we could add to any intranet where people could just retrieve an export of some database, and plot it with your code

Mosaic is designed for scale https://github.com/uwdata/mosaic https://idl.uw.edu/mosaic/
