Graph – Undirected graphs with self loops

Graph types

NetworkX provides data structures and methods for storing graphs.

All NetworkX graph classes allow (hashable) Python objects as nodes. and any Python object can be assigned as an edge attribute.

The choice of graph class depends on the structure of the graph you want to represent.

Which graph class should I use?

Graph Type NetworkX Class
Undirected Simple Graph
Directed Simple DiGraph
With Self-loops Graph, DiGraph
With Parallel edges MultiGraph, MultiDiGraph
