Hi; 
  
Is there a way to indicate the piechart to take into consideration the label font size to avoid having overlap between labels as in this example:  
http://jsfiddle.net/jordidebarcelona/fegf4zp5/1/ ? 
  
It seems that labels spacing is calculated asuming some fixed font size, but when a larger font size (for example 16px) is used, there is overlapping even when there is enught space to avoid it. 
  
Thanks for your help, 
  
       Jordi
