This example loads a GPX document and renders its content on the map using the built-in parser. It also shows how to configure styles for waypoints and tracks.
To work with GPX files, we need to load the API's mapsjs-data.js module. Then we use the H.data.gpx.Reader class, which downloads and parses the file. After that, we add a layer to the map using the H.Map#addLayer method to see the results.
