title: jVectorMap - setFocus error - jQuery
body: <p>I understand that the minified file from the zip is only the base code, and does not include libraries. Therefore I ran the <code>build.sh</code> file and it produced another minified file that I have included in my scripts. </p>
  
  <p><strong>Expectation:</strong></p>
  
  <p>I am attempting to zoom in on a marker when clicked. I have a function that runs on the event, <code>onMarkerClick</code>. </p>
  
  <p><strong>The problem:</strong></p>
  
  <p>I have looked at (2) different posts:</p>
  
  <ul>
  <li><p><a href="https://stackoverflow.com/questions/14728371/jvector-map-how-to-focus-on-a-marker">Jvector map, how to focus on a marker?</a></p></li>
  <li><p><a href="https://github.com/bjornd/jvectormap/issues/157" rel="nofollow noreferrer">https://github.com/bjornd/jvectormap/issues/157</a></p></li>
  </ul>
  
  <p>Both posts produce the same exact error.</p>
  
  <p><strong>The error:</strong></p>
  
  <p><code>Error: &lt;g&gt; attribute transform: Expected number, "scale(NaN) translate(N…".     jquery.jvectormap.min.js:733</code></p>
  
  <p>line 733 - <code>this.rootElement.node.setAttribute('transform', 'scale('+scale+') translate('+transX+', '+transY+')');</code></p>
  
  <p>Apparently <code>+scale+</code> is not a number (NaN)</p>
