Matplotlib – Drawing lattices and graphs with Networkx
To draw lattices and graphs with networkx, we can take the following steps −
- Import networkx and pyplot.
- Set the figure size and adjust the padding between and around the subplots.
- Use nx.grid_2d_graph(3, 3) to get a two-dimensional grid graph. The grid graph has each node connected to its four nearest neighbors.
- Draw the graph G with Matplotlib.
- To display the figure, use show() method.
Example
# Import networkx and pyplot
import networkx as nx
from matplotlib import pyplot as plt
# Set the figure size
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
# Draw the graph
G = nx.grid_2d_graph(3, 3)
nx.draw(G, node_size=100)
plt.show()
Output
It will produce the following output
