  3. Generate an API key and restrict it to your website to prevent unauthorized use.
  4. Include the Google Maps JavaScript API in your HTML file:

Creating Custom Icons

Creating custom icons for your map markers is the next step. You can design icons using graphic design software or find existing icons online. Here’s how to create custom icons:

  1. Use software like Adobe Illustrator or Canva to design your icon. Ensure that it is clear and recognizable.
  2. Export your icon in a web-friendly format (like PNG or SVG).
  3. Host the icon image on your web server or a reliable image hosting service.

Adding Custom Icons to Google Maps

Now that you have your custom icons ready, it’s time to add them to your Google Maps. Follow these detailed steps:

  1. Initialize the map in your JavaScript code:
function initMap() {
    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 10,
        center: {lat: -34.397, lng: 150.644}
    });
}
  1. Create a marker with your custom icon:
var marker = new google.maps.Marker({
    position: {lat: -34.397, lng: 150.644},
    map: map,
    icon: 'URL_TO_YOUR_CUSTOM_ICON'
});
  1. Add multiple markers as needed by repeating the marker creation step with different positions and icons.
