Notes

Requires Matplotlib.

Examples

>>> import numpy as np
>>> import matplotlib.pyplot as plt
>>> from scipy.spatial import ConvexHull, convex_hull_plot_2d

The convex hull of a random set of points:

>>> rng = np.random.default_rng()
>>> points = rng.random((30, 2))
>>> hull = ConvexHull(points)

Plot it:

>>> _ = convex_hull_plot_2d(hull)
>>> plt.show()
