Four Grids

Draw a graph with matplotlib.

import matplotlib.pyplot as plt
import networkx as nx

G = nx.grid_2d_graph(4, 4)  # 4x4 grid

pos = nx.spring_layout(G, iterations=100)

plt.subplot(221)
nx.draw(G, pos, font_size=8)

plt.subplot(222)
nx.draw(G, pos, node_color="k", node_size=0, with_labels=False)

plt.subplot(223)
nx.draw(G, pos, node_color="g", node_size=250, with_labels=False, width=6)

plt.subplot(224)
H = G.to_directed()
nx.draw(H, pos, node_color="b", node_size=20, with_labels=False)

plt.show()
