        <p>Display a map with the postcode boundaries overlay</p>
        This example displays a movable map initially centered on the <b>Brandenburg Gate</b> in 
        the centre of Berlin <i>(52.5159°N, 13.3777°E)</i> with the postcodes overlay provided by the 
        <a href="https://developer.here.com/documentation/platform-data/topics/what-is.html" target="_blank">Fleet Telematics Advanced Data Sets REST API</a>. 
        It's possible to display additional information about the postcode area by clicking on the marker.
    <div id="map"></div>
        The example uses <code>H.service.extension.platformData.TileProvider</code> class to fetch data 
        from the Fleet Telematics Advanced Data Sets service. Two providers are configured with the desired geometry 
        types (<code>H.service.extension.platformData.TileProvider.ResultType.POLYLINE</code> 
        for postcode borders and <code>H.service.extension.platformData.TileProvider.ResultType.MARKER</code> for postcode 
        centroids). The result is displayed on the map as two additional layers using an instance of the <code>H.map.layer.TileLayer</code>
         and <code>H.map.layer.MarkerTileLayer</code> correspondingly.
