API Key Security:
- Replace
"YOUR_API_KEY"with a valid Google Maps API key. Ensure the key is securely stored and not exposed in public repositories.
- Replace

var mapOptions = {
center: {lat: YOUR_LATITUDE || 40.7128, lng: YOUR_LONGITUDE || -74.006},
zoom: YOUR_ZOOM_LEVEL || 15
};
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
var markerOptions = {
position: {lat: YOUR_LATITUDE || 40.7128, lng: YOUR_LONGITUDE || -74.006},
