[![Join the chat at https://gitter.im/crossfilter/crossfilter](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/crossfilter/crossfilter?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [![Test status via Travis CI](https://travis-ci.org/crossfilter/crossfilter.svg?branch=master)](https://travis-ci.org/crossfilter/crossfilter) [![CDNJS](https://img.shields.io/cdnjs/v/crossfilter2.svg)](https://cdnjs.com/libraries/crossfilter2)

**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.

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 perfor­mance of live histograms and top-K lists. Crossfilter is available under the [Apache License](/square/crossfilter/blob/master/LICENSE).

This is a community-maintained fork of the original [square/crossfilter](https://github.com/square/crossfilter) library.
