This example loads data from a Mapbox Tileset.
A tileset is a collection of raster or vector data broken
up into a uniform grid of square tiles. A tileset can have
data within it.
If you use a VectorSource, make sure you use the `setSourceLayer()`
method, as is done below. This tells the Maps SDK to drill one level
deeper into the tileset and reference the correct data for the layer.
If you've created your own Mapbox account, you can find tilesets at
https://studio.mapbox.com/tilesets. You can make a GeoJSON-based
dataset at https://studio.mapbox.com/datasets, have Mapbox Studio
export the dataset to a tileset, and then use the tileset in your
project.
https://docs.mapbox.com/mapbox-gl-js/style-spec/sources/#vector
has more about a VectorSource. VectorSource objects are also used
in other examples in this app.
