Distribution can be shown as a dot distribution map. A Dot Map uses a form of a point symbol, its purpose is to show a continuous density through a discrete set of point symbols. Ideally, you would have a lot of detail information and select a location that characterizes the distribution (ex. keeping the dots along rivers or roads) This means that the dot map would require some hidden map layers.
