iplotx

iplotx (https://iplotx.readthedocs.io/) is a network visualisation library designed to extend the styling options for native NetworkX objects. It uses matplotlib behind the scenes, just like NetworkX’s internal functions, so it is compatible with all examples in the gallery while offering additional choices to customise your visualisation.

from collections import defaultdict
import matplotlib.pyplot as plt
import networkx as nx
import iplotx as ipx

G = nx.dense_gnm_random_graph(30, 40, seed=42)

# Get largest connected component
components = nx.connected_components(G)
largest_component = max(components, key=len)
H = G.subgraph(largest_component)

# Compute layout
layout = nx.kamada_kawai_layout(H)

ipx.network(
    H,
    layout,
    # Constant styling
    node_marker="s",
    node_edgecolor="black",
    node_linewidth=1.5,
    # Per-element styling, with fallback
    node_size=defaultdict(lambda: 17, {0: 50, 1: 30, 2: 40}),
    # Cycling styling
    node_facecolor=["lightblue", "steelblue", "dodgerblue"],
    node_label_color=["black", "white", "white"],
    # Add node labels
    node_labels=True,
    # Edge styling
    edge_alpha=0.7,
    edge_shrink=3,
    # Custom drawing order (nodes on top)
    edge_zorder=2,
    node_zorder=3,
    # Custom axes-level options
    margins=0.1,
    figsize=(8, 8),
)
plt.tight_layout()

Below is a minimal example with default settings:

ipx.network(H, layout)
