Exploring Datasets in Positron
summary
Positron ships a Data Explorer that actually handles massive tables — DuckDB powers billion‑row/backend queries and the UI works with millions of rows or thousands of columns without freezing. It uses a custom virtual data grid and prioritizes memory efficiency, instant scrolling, multi‑column sorting and filtering, column/row pinning, and live updates when code or CSV/Parquet files change. Summary pane shows histograms and value counts, there is convert‑to‑code for Python/R, and direct Ibis support is pending via an open PR.
