Sample 44428: Create a map of the United States and Mexico
 |  |  |  |  |  |
The sample code on the Full Code tab uses the SAS® 9.3 map data sets MAPS.STATES and MAPS.MEXICO to create a combined map of the U.S. and Mexico.
Since the map data comes from different map data sets, the boundaries between the U.S. and Mexico might not align exactly. In this case, the annotation around the U.S. and Mexico covers any border discrepencies that might exist.
