title: Google maps Geojson infowindow
body: <p>I am trying to build a website which displays certain meteor strikes throughout the last 200 years in Europe. I got the markers down but I'm having a hard time figuring out how to make them pop-up an info window with the rest of the information that is attached (mass, id, location etc.) can anyone help me out here?</p>
  <pre><code>  var map;
    function initMap() {
    map = new google.maps.Map(document.getElementById('map'), {
      zoom: 4,
      center: {lat: 45, lng: -1}
    });
  
    map.data.loadGeoJson(
        'Meteorite.geojson');
    }
    function information(results) {
    map.data.addGeoJson(results);
    map.data.addListener('click', function(e) {
      infowindow.setPosition(e.latLng);
      infowindow.setContent(e.feature.getProperty(&quot;id&quot;));
      infowindow.open(map);
    });
  }
  </code></pre>
