Big Data Performance

Benchmark the grid on datasets from one thousand up to two MILLION rows — pick a size and the sample data regenerates, the Web Worker re-initializes and the pivot recomputes, entirely in your browser. Columnar storage, a trie-based grouper and off-main-thread aggregation keep the UI responsive at every scale.

Try it: Choose a dataset size above the grid, then expand Regions and re-pivot — aggregation stays smooth even at 2,000,000 rows.
