LaTex Customized Sunburst

Question

This post is related to my previous one (which is still unsolved) link. Since I couldn't find a proper workaround, I'm here again asking for help for a variant version of the proposed sunburst (you find it in the above link).

In particular, a possible workaround is to define external boxes (the ones with bibliography entries) that do not follow the curvature. The following figures show in 2 the original output with the undesired curvature of hyperlinks, and in 3 the desired output that I'm currently looking for. The code used to generate the first figure can be found in 1.

The difference between the questions is not that clear, it would probably have been better simply to edit the previous one — David Carlisle, Dec 13 '21 at 14:06
Thank you for the feedback. I left the previous post open because I think it is still interesting to find possible solutions to the original question. I just modified this post, I hope I clarified what I'm looking for. — Luca, Dec 13 '21 at 14:12

You could just add a custom node by inserthing this piece of code at the end of the contents of the tikzpicture environment (and delete or comment out the other node which is replaced by this code):

\draw[black] (55:85pt) -- (55:115pt) arc (55:65:115pt)
 node[draw, anchor=south east] {\tiny\cite{einstein,dirac,knuth-fa,knuthwebsite}};

Maybe it is possible to use the \arcarrow macro defined in this code to draw the connecting line, but I did not fully understand how it is supposed to work (mainly because I didn't take the time to sufficiently study it), so I just ignored it.

Full code (taken from the linked question):
