d3.js: How to add value below the label in donut chart

I am new to d3.js and what I have achieved till now is, this using tutorials and videos.

Now I am trying to add the dataset.value below the label text as shown in the figure.

var dataset = [{
  label: 'On trip',
  value: 35
}, {
  label: 'parked',
  value: 65 
}];

How do I achieve this?
