NetworkX

Warnings

• breaking The 'release' module has been removed in NetworkX 3.0. Direct import of 'release' will result in an ImportError.
  Fix: Remove the import statement 'from networkx import release' from your code.
• deprecated The 'add_path' function is now a method of the Graph class and should be called on a Graph instance.
  Fix: Replace 'networkx.add_path(G, [0, 1, 2, 3])' with 'G.add_path([0, 1, 2, 3])'.
• gotcha Ensure that all optional dependencies (numpy, scipy, matplotlib, pandas) are installed for full functionality, especially for graph visualization and advanced computations.
  Fix: Install optional dependencies using 'pip install networkx[default]'.

Install

• pip install networkx Install NetworkX

Imports

• Graph

  from networkx import Graph

  Direct import of Graph class from networkx module.
• add_path

  G.add_path([0, 1, 2, 3])

  Use the method directly on a Graph instance.

Quickstart

A simple example to create a graph, add nodes and edges, and visualize it using matplotlib.

import networkx as nx

# Create an empty graph
G = nx.Graph()

# Add nodes and edges
G.add_nodes_from([1, 2, 3])
G.add_edges_from([(1, 2), (2, 3)])

# Draw the graph
import matplotlib.pyplot as plt
nx.draw(G, with_labels=True)
plt.show()
