Optionally truncate labels instead of hiding them entirely

[bnovc]

Is your feature request related to a problem? Please describe.
When you have fairly long labels, you get entirely empty cells

This makes reading the charts very difficult, and it means that sharing static screenshots of them isn't viable

Describe the solution you'd like
If a label doesn't fit, keep removing text from it until it does

Describe alternatives you've considered
Wrapping text could be helpful too, but there are other requests for that here, and I understand the challenge

Additional context
Add any other context or screenshots about the feature request here.

I accomplished this by adding in:

function angularTextMax(d) { var deltaAngle = state.angleScale(d.x1) - state.angleScale(d.x0); var r = Math.max(0, (state.radiusScale(d.y0) + state.radiusScale(d.y1)) / 2); var perimeter = r * deltaAngle; return perimeter / CHAR_PX_WIDTH; }

And using it allSlices.select('.angular-label').transition(transition$1).styleTween('display', function (d) {

Hi @bnovc, can you provide the missing code in the last block?
