Google Maps - marks and information windows for them

Question

Google Maps

Good day!
There is a table with coordinates, after receiving these coordinates, you need to add markers to the Google Maps map and attach a specific info window to each marker, tell me how to do this? Here are my work:

var gmap = {
  map : [],
  markers : [],

  init : function(){
    var mapOptions = {
      zoom: 15,
    };
    map = new google.maps.Map(document.getElementById('map-canvas'),
        mapOptions);

    google.maps.event.addListener(map, 'click', function(coordinates) {
      var coords = {
        lat : coordinates.latLng.d,
        lng : coordinates.latLng.e,
      };
      gmap.addMarker(map,coords);
    });

    gmap.geo();
  },

  loadMarkers : function(data){
    /* как сделать вывод маркеров и инфоокон? */
  }

  addMarker : function(mapObj,coords){
    
    var marker = new google.maps.Marker({
      	position: coords,
      	map: mapObj,
      	icon: 'img/marker-32x32.png',
      	animation: google.maps.Animation.DROP,
    });
    
    listener.tmp.marker = marker; //удалит маркер, если модальное окно будет закрыто
    dialog.addPlace(marker);
  },

  deleteMarker : function(marker){
    marker.setMap(null);
  },

  geo : function(){
    // Try HTML5 geolocation
    if(navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(function(position) {
        var pos = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);

        var infowindow = new google.maps.InfoWindow({
          map: map,
          position: pos,
          content: 'Location found using HTML5.'
        });
        map.setCenter(pos);
      }, function() {
        gmap.geoError(true);
      });
    } else {
      // Browser doesn't support Geolocation
      gmap.geoError(false);
    }
  },

  geoError : function(errorFlag) {
    if (errorFlag) {
      var content = 'Error: The Geolocation service failed.';
    } else {
      var content = 'Error: Your browser doesn\'t support geolocation.';
    }

    var options = {
      map: map,
      position: new google.maps.LatLng(-34.397, 150.644),
      content: content
    };

    var infowindow = new google.maps.InfoWindow(options);
    map.setCenter(options.position);
  },
};



google.maps.event.addDomListener(window, 'load', gmap.init);

the functionality should be written either in the loadMarkers function or in the html code
pS: I know what to run through foreach, the question is what to run in order to get markers on the map and info windows for them (when clicking on the market)
