This example demonstrates a full-screen interactive map centered on Lubbock, Texas, using the Leaflet JavaScript library. It loads two base layers: an OpenStreetMap tile service and a Google satellite tile layer, with the latter supporting subdomains and a maximum zoom level. A marker is placed at the city’s coordinates, bound to a popup that opens immediately, displaying the label "Lubbock." The map is initialized with the Leaflet `map` function, and both tile layers and the marker are added via the `addTo` method, showcasing basic layer and popup management.
