Fast Multidimensional Filtering for Coordinated Views
Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; it was built to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly.
Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the perforÂmance of live histograms and top-K lists.
