Cross-posted from Stack OverflowIt's taking almost 2 minutes to load all the pins on this Google Maps API. Every time the page is loaded it sends a request for each location one by one. Can it do this all at the same time? Or preload the map beforehand? How can make this load faster?<head>  <script type=text/javascript src=https://www.gstatic.com/charts/loader.js></script>  <script type=text/javascript>    google.charts.load('current', {      'packages': ['map'],      // Note: you will need to get a mapsApiKey for your project.      // See: https://developers.google.com/chart/interactive/docs/basic_load_libs#load-settings      'mapsApiKey': 'some api key'    });
