Drawing a Network Graph with NetworkX and Matplotlib

To draw a network graph with networkx and matplotlib, plt.show() −

• Set the figure size and adjust the padding between and around the subplots.

• Make an object for a dataframe with the keys, from and to.

• Get a graph containing an edgelist.

• Draw a graph (Step 3) using draw() method with some node properties.

• To display the figure, use show() method.

Example

import pandas as pd
import networkx as nx
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
df = pd.DataFrame({'from': ['A', 'B', 'C', 'A'], 'to': ['D', 'A', 'E', 'C']})
G = nx.from_pandas_edgelist(df, 'from', 'to')
nx.draw(G, with_labels=True, node_size=100, alpha=1, linewidths=10)
plt.show()
