  <p>I am using google map as a white empty map displaying only the markers 
  what I need to do is display the countries borders with their labels 
  I used a custom styled map like so : </p>
  
  <pre><code>  var styleArray =
                  [
  
                      {
                          featureType: "all",
                          stylers: [{ visibility: "off" }]
                      },
                      {
                          featureType: "road",
                          stylers: [{ visibility: "off" }]
                      }
  
                  ];
  
  
  map.set('styles', styleArray);
  </code></pre>
  
  <p>How can i achieve this ?</p>
