d3.js: Change label from text to html (foreignObject)

Hi Community,

I’m still working on a customization of the “Zoomable Sunburst” example. Now I want to highlight the text. Maybe by adding some font-awesome icons based on another json object. It seems like this could be handled by integration of “foreignObject”.
It would be very nice if anyone could help my at this certain example. I’m very open to other suggestions as well.

Kind regards
