Grapher can import TIGER/Line .RT* files. A TIGER/Line file dataset usually includes many .RT* files in a single directory. TIGER/Line files are extracts of selected geographic and cartographic information from the Census TIGER® database. TIGER/Line vector files include point, polyline, and polygon features that represent land attributes and political or statistical areas, such as boundaries, census tracts, roads, cities, rivers, etc. TIGER/Line files contain only geographic information, but can be linked to United States Census Bureau demographic data for analysis.
The TIGER/Line file format is a text-based format. The TIGER/Line file format was replaced by a shapefile specification in 2008.
