  <pre><code> var shape = {
                coords: [1, 1, 1, 30, 30, 30, 30, 1],
                type: 'poly'
                };  
  
   this.marker = new google.maps.Marker({
                  map: map,
                  position: {
                      lat: parseFloat(company.latitude),
                      lng: parseFloat(company.longitude)
                  },
                  shape:shape,
                  icon: {
                      url: '/src/images/blue_marker.png',
                      size: new google.maps.Size(30, 30),
                      scaledSize: new google.maps.Size(30, 30)
                  },
                  title: company.name + ' ' + company.vacancy.vacancy
