Hello

I like your example and was migrating to the new version of d3.js to version 4, so that it was updated.

And I've encountered a series of problems that I've been solving, changing the line 216 of your code, from .attr ("width", x1.rangeBand ()) to .attr ("width", x1.bandwidth )).

The problem has been that it has skipped another error and not followed, I have commented for example line 223 of my .style file ("fill", function (d) {return color (d.Name);}) so that it will start to see something.

If you could help me advance this update, I upload the file
