Parameters
----------
polygons : list of dict
List of dictionaries containing the polygon properties.
The following properties can be specified in the dict.
* points (list): XY(Z) coordinates of the polygon vertices.
* text (str, optional): The text of the label. Default is ``None``.
* textcolor (rgb tuple or hex string, optional): Color of the label text. Default is black.
* fontsize (int, optional): The size of the font of the label text. Default is ```12``.
* facecolor (rgb tuple or hex string, optional): Color of the polygon face. Default is white.
* edgecolor (rgb tuple or hex string, optional): Color of the edge of the polygon. Default is black.
* edgewidth (float): Width of the polygon edge. Default is ``1.0``.
Returns
-------
object
The matplotlib polygon collection object.
