What are the three type groups of vector data?

Vector data use three geometric primitives: points, lines, and polygons. Points represent discrete locations, lines model linear features made of connected vertices, and polygons define area extents bounded by rings. Imagery, by contrast, is raster data, not a vector geometry, so it isn’t a vector type. That’s why the standard vector data set consists of points, lines, and polygons, while imagery does not belong in that group. This distinction helps explain why a option that includes imagery isn’t correct.
