      This sample showcases the use of <a href="https://protomaps.com/" target="_blank">Protomaps</a> to display <a href="https://overturemaps.org/" target="_blank">Overture</a> places data on a map.
      The data is stored in a PMTiles file that contains a vector tileset of places data. The data is filtered by category and displayed as symbols on the map.
      Click on a symbol to view more information about the place.
