The Square folks have officially given up on supporting their version of the crossfilter.js library. Some of the team that works on dc.js helped make a dedicated crossfilter organization that maintains a crossfilter2 version on npm ( https://www.npmjs.com/package/crossfilter2 ) and github ( https://crossfilter.github.io/crossfilter/ ).

I don't believe there's anything really wrong with the old library yet, but the new version has moved on with a few new feature additions and bug fixes.

This looks like some promising work, but it also looks like it was worked on briefly for a year ago and then left to gather dust. I only found it via a link from here: https://github.com/plotly/public-health/blob/master/README.md#3-open-sourcing-crosslink-plotlyjs-library

Is documenting and supporting this anywhere on a current roadmap for plotly devs? Was there a decision to go a different direction with chart interactions and I just missed that (entirely possible)?

Thanks for all the great work regardless.
