    // config goes here... 
  }).dxVectorMap('instance');

  // remove the border around the map
  $("#mapContainer").children("svg:first").children("rect:first").attr("stroke-width", "0");
  
  // you can also change the color of the border
  // make sure you set the stroke-width to a non-zero value so it shows up
  $(mapContainerSelector).children("svg:first").children("rect:first").attr("stroke", "#ff0000"); // make border red
