y) r a A geometry type that represents a single coordinate.
Each coordinate has x, y and possibly z and/or m values.
A point is a zero-dimensional feature and has zero length and zero area.
Parameters
----------
args : float, or sequence of floats
The coordinates can either be passed as a single parameter, or as
individual float values using multiple parameters:
1) 1 parameter: a sequence or array-like of with 2 or 3 values.
2) 2 or 3 parameters (float): x, y, and possibly z.
Attributes
----------
x, y, z, m : float
Coordinate values
Examples
--------
Constructing the Point using separate parameters for x and y:
>>> from shapely import Point
>>> p = Point(1.0, -1.0)
Constructing the Point using a list of x, y coordinates:
>>> p = Point([1.0, -1.0])
>>> print(p)
POINT (1 -1)
>>> p.y
-1.0
>>> p.x
1.0

Parameters
----------
scale_factor : float
Multiplication factor for the SVG circle diameter. Default is 1.
fill_color : str, optional
Hex string for fill color. Default is to use "#66cc99" if
geometry is valid, and "#ff3333" if invalid.
opacity : float
Float number between 0 and 1 for color opacity. Default value is 0.6
