title: Embedding link into SGV inside .attr
body: <p>The following is a part of the javascript of an SVG I am working on,</p>
  
  <pre><code>  var clockCenter = this.s.circle(200, 200, 5);
    clockCenter.attr({
      fill: "#DDD",
      stroke: "transparent",
      strokeWidth: 30
    });
  </code></pre>
  
  <p>And I want to embed a code inside this attribute to direct the user to <code>http://example.com</code> by clicking the SVG image. How can I do this?</p>
  
  <p>Thanks!</p>
