Digital line graphs are maps that contain a variety of different information such as boundary lines, roads, and other topography.  This is digital vector data because data about map features are stored as lines, points, and areas.  This type of map is also from the United States Geological Survey.  The different scales present allow the map to portray a variety of information.  In this map, state and county boundary lines are shown.  This map also has colors that could represent different things such as average temperature or elevation.
