<div id="dvMap" style="width: 100%; height:350px;">
                       </div>
                       <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAEYPGjyMXdnZ9Sq2VOyqvf1TLotaBCDx"></script>
                       <script type="text/javascript">
       var markers = @Html.Raw(ViewBag.Markers);
       window.onload = function () {
           var mapOptions = {
               center: new google.maps.LatLng(markers),
               zoom: 15,
               mapTypeId: google.maps.MapTypeId.ROADMAP
           };
           var infoWindow = new google.maps.InfoWindow();
           var map = new google.maps.Map(document.getElementById("dvMap"), mapOptions);
           for (i = 0; i < markers.length; i++) {
               var data = markers[i]
               var myLatLng = new google.maps.LatLng(data.lat, data.lng);
               var marker = new google.maps.Marker({
