Label in Children doesn't work

[poulakidask]

const TREE = {
  value: 100,
  label: 'item A',
  children: [{
            value: 50,label: 'item B'
  	}, 
       {
            value: 30,label: 'item C'
       }, 
       {
           value: 20,label: 'item D'
     }]
};

How can I make the label to be displayed for the children as well?

Update

The labels seem to be displayed but one on top of the other, in the centre of the chart! So, only the very first Label can be read.

Any idea how to position them on top of the corresponding arc?
