Is there a way to make each individual box a clickable link? Could you use JSON data to bind to each box? If so how?

I did get the Voronoi to work with JSON data. I posted it at this link https://github.com/davefaliskie/voronoi_with_json I used Ruby on Rails, however the modified code from christophermanning can be found in assets -> javascripts -> d3_scripts.js
