For degenerate input, including collinearity and other violations of general position, it may be preferable to calculate the Voronoi diagram with Qhull options ``QJ`` for random joggling, or ``Qt`` to enforce triangulated output. Otherwise, some Voronoi regions may not be visible. Examples -------- >>> import numpy as np >>> import matplotlib.pyplot as plt >>> from scipy.spatial import Voronoi, voronoi_plot_2d Create a set of points for the example: >>> rng = np.random.default_rng() >>> points = rng.random((10,2)) Generate the Voronoi diagram for the points: >>> vor = Voronoi(points) Use `voronoi_plot_2d` to plot the diagram: >>> fig = voronoi_plot_2d(vor) Use `voronoi_plot_2d` to plot the diagram again, with some settings customized: >>> fig = voronoi_plot_2d(vor, show_vertices=False, line_colors='orange', ... line_width=2, line_alpha=0.6, point_size=2) >>> plt.show() rr9rr,zVoronoi diagram is not 2-D show_pointsT point_sizeN.) markersize show_verticesr- line_colorsr@ line_widthg? line_alpharrA)rBlwalpharCdashed)rDr:r&r.r/getr1verticesmeanr r!zip ridge_pointsridge_verticesasarrayallappendlinalgnormarraysigndot furthest_siteabsr#r"rEr*r)vorrrr:rIrMrNrOcenter ptp_boundfinite_segmentsinfinite_segmentspointidxr=itnmidpoint direction aspect_factor far_points r rrssH655555 za5666 vvmT""PVVL$//   111a4 #*QQQT"2CJOOO vvot$$=  QQQT"CLA$6<<<&&,,K c**J c**J Z__!_ $ $Fsz***IO !133EFFCC'*W%% 6'Q,   C  " "3<#8 9 9 9 91 %a(A 8A;'#*Xa[*AAA "" "A1Q4%1''Az(+00a088Hx&'8! < <==AI!
