Zoomable Sunburst on d3.js v4
license: gpl-3.0

I and Serhii Pahuta rewrote Mike Bostock's Zoomable Sunburst to newer version 4 of d3.js library. All functionality remains the same.

Click on any arc to zoom in, and click on the center circle to zoom out. Permanent link.

This is really great. Thanks for putting the conversion together. Do know of a way to add labels to the sectors?

I've successfully added labels, but they don't work with the transitions. Is there an example of this anywhere?
