Notes

Requires Matplotlib.

Examples

Set of point:

>>> import matplotlib.pyplot as plt
>>> rng = np.random.default_rng()
>>> points = rng.random((10,2))

Voronoi diagram of the points:

>>> from scipy.spatial import Voronoi, voronoi_plot_2d
>>> vor = Voronoi(points)

using voronoi_plot_2d for visualisation:

>>> fig = voronoi_plot_2d(vor)

using voronoi_plot_2d for visualisation with enhancements:

>>> fig = voronoi_plot_2d(vor, show_vertices=False, line_colors='orange',
...                 line_width=2, line_alpha=0.6, point_size=2)
>>> plt.show()
