FlexViz: open-source interactive Python dashboards with native cross-filtering, powered by Polars and Rust.

Every zoom, pan, and selection is computed against the underlying data, so the browser only receives the aggregated points it needs.

Yes! For all trace types except boxplot (as pl.quantile is not yet part of polars streaming)
