title: How can I select :last-child in d3.js?
body: <p>I need to manipulate the <code>text</code> elements of the first and last tick of an axis to bring them more towards the center.</p>
  
  <p>I am trying to select them, one at the time, with something like <code>svg.select('.tick:last-child text')</code> but it doesn't work. I'd then apply <code>.transform('translate(4,0)')</code>...</p>
  
  <p>Am I doing something wrong? How can I achieve this?</p>
