title: How to set zoomLevel in google Visualization Map api?
body: <p>I am trying to implement visualization map api,following this link <a href="https://developers.google.com/chart/interactive/docs/gallery/map" rel="nofollow">https://developers.google.com/chart/interactive/docs/gallery/map</a></p>
  
  <p>i am successfully drawing the point on the google map but not able to set the zoomlevel.
  For single point the zoomlevel automatic set to 19(max level).</p>
  
  <p>my code:-</p>
  
  <pre><code>var map = new google.visualization.Map(document.getElementById('map_div'));
  
  map.draw(data, {showTip: true, zoom:14,  mapType: 'normal', useMapTypeControl:true, enableScrollWheel:false});
  </code></pre>
  
  <p>I have tried this <code>map.setZoom(12)</code> but its not working. </p>
