对记录进行快速的 n 维过滤和分组。「Fast n-dimensional filtering and grouping of records.」
Crossfilter 是一个 JavaScript 库，用于在浏览器中探索大型多变量数据集。Crossfilter 支持极快（<30ms）的协调视图交互，即使是包含百万条或更多记录的数据集。
由于大多数交互只涉及单一维度，然后只对过滤值进行小幅调整，因此增量过滤和还原比从头开始要快得多。Crossfilter 使用排序索引（以及小技巧）来实现这一点，极大地提高了实时直方图和 top-K 列表的性能。Crossfilter 采用 Apache 许可协议。
这是一个社区维护的原始 square/crossfilter 库的分叉。

这个包可以在 npm 中以 crossfilter2 为名找到。
npm install crossfilter2
安装依赖项：
npm install
用 npm test 测试更改。使用 npm run build 进行构建以在浏览器中使用。你可能还想用 npm run benchmark 对你的改动进行基准测试。

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.
This is a community-maintained fork of the original square/crossfilter library.
