crossfilter

Achieves sub-30ms response times for filtering and grouping, as stated in the README, enabling smooth interactions even with million-record datasets.

Uses sorted indexes and bit-twiddling hacks to manage datasets with over a million records directly in the browser without performance lag.

Only recalculates affected dimensions when filters adjust, making coordinated view updates significantly faster than full recalculations.

Enables seamless interaction across multiple linked visualizations like histograms and top-K lists, ideal for interactive dashboards and data exploration.
