Visualize NetworkX Graph#

This example demonstrates how to visualise a NetworkX graph using a VisPy Graph.

import sys

import networkx as nx

from vispy import app, scene
from vispy.visuals.graphs import layouts

canvas = scene.SceneCanvas(title='Simple NetworkX Graph', size=(600, 600),
                           bgcolor='white', show=True)
view = canvas.central_widget.add_view('panzoom')

graph = nx.adjacency_matrix(
    nx.fast_gnp_random_graph(500, 0.005, directed=True))
layout = layouts.get_layout('force_directed', iterations=100)

visual = scene.visuals.Graph(
    graph, layout=layout, line_color='black', arrow_type="stealth",
    arrow_size=30, node_symbol="disc", node_size=20,
    face_color=(1, 0, 0, 0.2), border_width=0.0, animate=True, directed=False,
def on_draw(event):
    if not visual.animate_layout():
