title: How can I display distance markings on a line (Mapbox-gl)?
body: <p>I want to display kilometers markings along a route drawn with addlayer: line. With @turf/along, I can calculate the coordinates for the distance markings, but what would be a good way of displaying them on the map? Non-turf related methods are also welcome.</p>
  
  <p>I want to display the coordinates either on the route line itself, or below the line between a certain meter span, like per 100m.</p>
