title: Linking circles to anchors
body: <p>I created anchors in a table, inserting. <code>&lt;tr id="link_i&gt;</code> for each line.
  the json contains a lot of  <code>"link":"#link_i</code>
  My code is below :
  ...</p>
  
  <pre><code>circles
  .attr("xlink:href",function(d) { return d.link; })
  .on("mouseover",function(d,i){ tooltip.style("visibility","visible");return tooltip.text(d.title);})
  .on("mouseout",function(){return tooltip.style("visibility","hidden");})
  
  ...
  </code></pre>
  
  <p>The svg graph with a lot of circles works fine, showing each specific "title" when the mouse is over the different circles, but when I click on any circle, the link doesn't move the page down to the specified anchor ...
  Does anyone has an idea ?</p>
