    Point is represented by its X and Y coordinates, stored as a Tuple(, Float64).

    Example

    Result:

    1. │ (10,10) │ Point         │
    2. └───────┴───────────────┘

    is a simple polygon without holes stored as an array of points: (Point).

    Example

    Query:

    Result:

    1. ┌─r─────────────────────────────┬─toTypeName(r)─┐
    2. │ [(0,0),(10,0),(10,10),(0,10)] │ Ring          │

    Example

    This is a polygon with one hole:

    Result:

    2. │ [[(20,20),(50,20),(50,50),(20,50)],[(30,30),(50,50),(50,30)]] │ Polygon        │
    3. └───────────────────────────────────────────────────────────────┴────────────────┘

    MultiPolygon consists of multiple polygons and is stored as an array of polygons: (Polygon).

    Example

    Result:

    1. ┌─mpg─────────────────────────────────────────────────────────────────────────────────────────────┬─toTypeName(mpg)─┐
    2. └─────────────────────────────────────────────────────────────────────────────────────────────────┴─────────────────┘
