SAS Enterprise Guide has a wizard (Graph|SAS Enterprise Guide has a wizard (Graph|Map) to plot data onto a map.Map) to plot data onto a map.

SAS/GRAPH is a required product for SAS/GRAPH is a required product for maps.maps.

SAS/GRAPH includes SAS datasets that SAS/GRAPH includes SAS datasets that contain geographic data such as ZIP and contain geographic data such as ZIP and FIPS codes. FIPS codes.

An important variable for mapping is An important variable for mapping is _MAP_GEOMETRY_._MAP_GEOMETRY_.
