dc.js is a JavaScript charting library with native Crossfilter support that fosters highly efficient exploration of large multi-dimensional datasets (inspired by Crossfilter's demo). It leverages D3.js to render charts in the CSS-friendly SVG format, and it works best with flattened data. Charts rendered using dc.js are naturally data-driven and reactive, and therefore provide instant feedback to users' interactions.
