title: D3.js fixed position group in chord diagram
body: <p>I am looking for a way to have a fixed position and width of a group in a d3.js chord diagram. Is there a way to do this?</p>
  
  <p><strong>This is how it is shown by default when drawing the chord diagram:</strong></p>

  <p><strong>This is how I would like the top (1st group) to show (wider than the other groups and centered at the top):</strong></p>
