This is an updated version of this demo of the crossfilter library. Crossfilter has been one of my favorite - and what I think to be on of the most underrated - JavaScript libraries. It hasn't seen much of any updates in quite a while, so I wanted to find out how it would work with version 4 of d3.js.
There were some issues that came up with how d3-brush has been updated for v4. Big thanks goes to Alastair Dant (@ajdant) for helping to figure out a couple of those issues!
Also worth reading, is this discussion started by Robert Monfera (@monfera).
