Today's infographic comes by way of Stephen Von Worley, an American guy who has a lovely website called Datapointed.net. The site is a festive use of visualizations to explain or track social and historical stuff.
Von Worley went to some trouble looking for a way to display the near-total presence of McDonald's in the United States. Using help from a site called AggData, the map here is his attempt to visualize the broad swath that is Mickey Dee's.
Each bright spot is a location with one or more McDonald's.
