   I have also encountered the same problem with the library. In our area of 
field, we are using the sunburst to plot z scores for subdomains and domains. 
The domain's value is the mean of the z score of the subdomain which are its 
children. Therefore, the domain's value is always less then the sum of value of 
its subdomains.
   We can't really hack around it with the formatter label (by modifying the 
displayed label with a different value), since we are using visualmaps to plot 
colors.
   I would propose that an option should be available to disable the link 
between value and radius of a sunburst element. By doing this, we could put 
whatever value we want for parents and children and not have any problem with 
rendering while still having the possibility to have the correct color shown 
through visualmap.
   
   Basically it would be great to have this rendering:
