Add a circle layer to the map

add_circle_layer(map, source = NULL, filter = NULL,
  circle_blur = NULL, circle_color = NULL, circle_opacity = NULL,
  circle_pitch_alignment = NULL, circle_pitch_scale = NULL,
  circle_radius = NULL, circle_sort_key = NULL,
  circle_stroke_color = NULL, circle_stroke_opacity = NULL,
  circle_stroke_width = NULL, circle_translate = NULL,
  circle_translate_anchor = NULL, visibility = TRUE, popup = NULL,
  id = "circle-layer")

`map`	A mapboxer object.
`source`	A Mapbox source. Uses the source from the mapboxer object if no source is supplied.
`filter`	A filter expression that is applied to the `source`.
`circle_blur`	(paint) Amount to blur the circle. 1 blurs the circle such that only the centerpoint is full opacity.
`circle_color`	(paint) The fill color of the circle.
`circle_opacity`	(paint) The opacity at which the circle will be drawn.
`circle_pitch_alignment`	(paint) Orientation of circle when map is pitched. One of "map", "viewport".
`circle_pitch_scale`	(paint) Controls the scaling behavior of the circle when the map is pitched. One of "map", "viewport".
`circle_radius`	(paint) The radius of the circle.
`circle_sort_key`	(layout) Sorts features in ascending order based on this value. Features with a higher sort key will appear above features with a lower sort key.
`circle_stroke_color`	(paint) The stroke color of the circle.
`circle_stroke_opacity`	(paint) The opacity of the circle's stroke.
`circle_stroke_width`	(paint) The width of the circle's stroke. Strokes are placed outside of the `circle_radius`.
`circle_translate`	(paint) The geometry's offset. Values are [x, y] where negatives indicate left and up, respectively.
`circle_translate_anchor`	(paint) Controls the frame of reference for `circle_translate`. One of "map", "viewport".
`visibility`	(layout) Whether the layer should be displayed.
`popup`	A mustache template in which the tags refer to the properties of the layer's data object.
`id`	The unique id of the layer.
