A self-loop is an edge that originates from and terminates the same node.
This example shows how to draw self-loops with
import networkx as nx import matplotlib.pyplot as plt # Create a graph and add a self-loop to node 0 G = nx.complete_graph(3, create_using=nx.DiGraph) G.add_edge(0, 0) pos = nx.circular_layout(G) # As of version 2.6, self-loops are drawn by default with the same styling as # other edges nx.draw(G, pos, with_labels=True) # Add self-loops to the remaining nodes edgelist = [(1, 1), (2, 2)] G.add_edges_from(edgelist) # Draw the newly added self-loops with different formatting nx.draw_networkx_edges(G, pos, edgelist=edgelist, arrowstyle="<|-", style="dashed") plt.show()
