Map Critique #9

This is a proportional symbol map of the individuals in USA who are not committed. This is one of the most interesting and unusual map. 

One obvious mistake in this map is that the cartographer didn't provided a title and a scale. This map would also be better if there is an inset. Eventhough USA is famous, an inset must still be provided in order to emphasize where it is actually on the world map. 

Also, the cartographer provided a label on selected cities only. He/she must provide the labels for all city or do not put label on any.
