title: Angular-UI tooltips on d3.js svg elements
body: <p>Hey I´m trying to use Angular UI tooltips on d3.js SVG elements. I´m generating the elements in a controller.</p>
  
  <pre><code> context.selectAll("circle")
    .data(data)
    .enter()
    .append("svg:circle")
    .attr("tooltip-append-to-body", true)
    .attr("tooltip", function(d){
               return d.name;
           })
  </code></pre>
  
  <p>The elements and tooltip attributes in the code are shown correctly, but no tooltips appear.<br>
  When I add tooltips in HTML it is working properly.</p>
