title: How to retrieve delicious related tags
body: <p>I have found this example <a href="http://hublog.hubmed.org/archives/001049.html" rel="nofollow">here</a> which uses delicious related tags and create a graph. But I don't know how they implemented it. I don't know how to get a list of related tags from delicious API, because in the documentation it is not mentioned at all, but in delicious <a href="http://delicious.com/" rel="nofollow">website</a> when you search for a tag it shows related tags in the right hand. </p>
  
  <p>Does anybody know how to get related tags using API?</p>
  
  <p>Thank you</p>
