What is "geo_countries" in the geom command and what could be another option for that spot?

Explanation:

In the context of the command | geom geo_countries featureIdField=VendorCountry, "geo_countries" refers to a type of dataset or object within a geospatial visualization command in a data analytics platform or software. It usually represents a predefined shape or boundary data for countries which can be used to create maps. The featureIdField specifies which field in the dataset should be used to match the shapes in "geo_countries" with their corresponding data records.

Another option for this spot could be "geo_states", "geo_cities", or any other geospatial object that contains different kinds of shape data, such as states, regions, or custom boundaries based on the dataset and requirements of the visualization. The specific alternatives depend on the software or library in use and the available geospatial objects within it.
