Markers reprensent points of interest on a map. Markers need to be placed on a layer (a ClutterGroup). Layers have to be added to a ChamplainView for the markers to show on the map.
A marker is nothing more than a regular ClutterActor. You can draw on it what ever you want. Don't forget to set the anchor position in the marker using champlain_marker_set_anchor. Set the markers position on the map using champlain_marker_set_position.
Champlain has a default type of markers with text. To create one, use champlain_marker_new_with_label.
