title: add marker to ammap map
body: <p>I want to add a circular marker to an <a href="http://www.ammap.com/" rel="nofollow noreferrer">ammap</a> map. The marker should be centered on Berlin, which has latitude 52.523407 and longitude 13.4114 (you can verify these coordinates <a href="http://itouchmap.com/latlong.html" rel="nofollow noreferrer">here</a>).</p>
  
  <p>Here's the source code of a page that attempts this. A <a href="http://jsfiddle.net/6c5U3/589/" rel="nofollow noreferrer">jsFiddle example</a> is also avaialble.</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  
  &lt;script src="ammap.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="germanyLow.js" type="text/javascript"&gt;&lt;/script&gt;
  
  &lt;script type="text/javascript"&gt;
  
      var dataPoints = [{
              latitude: 52.523407,
              longitude: 13.4114,
              type: 'bubble',
              color: '#CC0000',    
              fixedSize: false,
              alpha: 0.5,
              height: 50,
              width: 50
      }];
  
      AmCharts.ready(function() {
          // create AmMap object
          var map = new AmCharts.AmMap();
  
          // set path to images
          map.pathToImages = "images/map";
  
          var dataProvider = {
              mapVar: AmCharts.maps.germanyLow,
              getAreasFromMap:true,
              images: dataPoints
          }; 
  
          // pass data provider to the map object
          map.dataProvider = dataProvider;
  
          map.areasSettings = {
              autoZoom: true,
              selectedColor: "#CC0000"
          };
  
          // write the map to container div
          map.write("mapdiv");                           
      });
  
  &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;    
      &lt;div id="mapdiv" style="width: 600px; height: 400px;"&gt;&lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;

  <p>If you open this page you see the following. I've added the black arrow myself to indicate where the circle should be located. As you can see the centre of the circle is about 150km north-west of it should be. If I add other markers they are also positioned about 150 km NW of where I would expect them to be. Am I doing something wrong, or is this a bug?</p>
