 Geography is a data type composed of latitude and longitude that represents geospatial information. Nebula Graph currently supports Point, LineString, and Polygon in [Simple Features](https://en.wikipedia.org/wiki/Simple_Features) and some functions in [SQL-MM 3](https://www.techrepublic.com/index.php/resource-library/whitepapers/sql-mm-spatial-the-standard-to-manage-spatial-data-in-relational-database-systems/), such as part of the core geo parsing, construction, formatting, conversion, predicates, and dimensions.
