title: Append DOM element to the D3
body: <p>I'm using D3 for drawing on the SVG. What I want is to append DOM element or HTML to the D3, like:</p>
  
  <pre><code>task.append(function(model){
  //here return html or dom
  };
  </code></pre>
  
  <p>Documentation says it's possible, but unfortunately I can't find any example or found out how to do this myself.</p>
