  You can access an existing circle style layer using the
  `-[MGLStyle layerWithIdentifier:]` method if you know its identifier;
  otherwise, find it using the `MGLStyle.layers` property. You can also create a
  new circle style layer and add it to the style using a method such as
  `-[MGLStyle addLayer:]`.
