How to reshape a networkx graph in Python?

To reshape a networkx graph in Python, we can take the following steps −

Create a data frame using Panda's data frame.
Return a graph from Pandas DataFrame containing an edge list using from_pandas_edgelist() method.
Draw the graph G with matplotlib. We can reshape the network by increasing and decreasing the list of keys "from" and "to".
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"] = [7.00, 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=150, alpha=0.5, linewidths=40)
plt.show()
