Plot the given Delaunay triangulation in 2-D

Parameters:

tri : scipy.spatial.Delaunay instance

Triangulation to plot

ax : matplotlib.axes.Axes instance, optional

Axes to plot on

Returns:

Notes

Requires Matplotlib.

Examples

>>> import matplotlib.pyplot as plt
>>> from scipy.spatial import Delaunay, delaunay_plot_2d

The Delaunay triangulation of a set of random points:

>>> points = np.random.rand(30, 2)
>>> tri = Delaunay(points)

Plot it:

>>> _ = delaunay_plot_2d(tri)
>>> plt.show()
