def draw_points(self, points):
"""Draws points on a 2D plot.
Parameters
----------
points : list of dict
List of dictionaries containing the point properties.
Each point is represented by a circle with a given radius.
The following properties of the circle can be specified in the point dict.
* pos (list): XY(Z) coordinates
* radius (float, optional): the radius of the circle. Default is 0.1.
* text (str, optional): the text of the label. Default is None.
* facecolor (rgb or hex color, optional): The color of the face of the circle. Default is white.
* edgecolor (rgb or hex color, optional): The color of the edge of the cicrle. Default is black.
* edgewidth (float, optional): The width of the edge of the circle. Default is 1.0.
* textcolor (rgb or hex color, optional): Color of the text label. Default is black.
* fontsize (int, optional): Font size of the text label. Default is 12.
Returns
-------
object
The matplotlib point collection object.
