voronoi_plot, a Python code which plots the Voronoi neighborhoods of a set of center points.
The picture is created using discrete pixel geometry, rather than sophisticated analysis. In other words, each center point is assigned a color at random. Then each pixel in the image is colored the same as the nearest center point.
The code allows the user to choose the values of M and N, the number of rows and columns used in the pixel array.
The code allows the user to choose the LP norm in which distances are calculated, with P any positive real value. In particular
The scipy.spatial.Voronoi() and voronoi_plot_2d() commands can together create and plot a Voronoi diagram when the Euclidean norm is used to measure distance, but they do not have the ability to deal with other norms. This code gives a simple way of viewing such cases.
