Draw NetworkX graphs with Altair

Project description


Draw NetworkX graphs with Altair

Gitter chat

nx_altair offers a similar draw API to NetworkX but returns Altair Charts instead.

If you'd like to contribute, join the Gitter chatroom and share your ideas! Also, checkout the to-do list below.


If you'd like to start playing with nx_altair, download this notebook!

Simple graph

import networkx as nx
import nx_altair as nxa

# Generate a random graph
G = nx.fast_gnp_random_graph(n=20, p=0.25)

# Compute positions for viz.
pos = nx.spring_layout(G)

# Draw the graph using Altair
viz = nxa.draw_networkx(G, pos=pos)

# Show it as an interactive plot!

Leverage Altair

Customize the visualization

nx_altair also supports many of the same arguments from NetworkX for styling your network--with an Altair twist! Map visualization attributes in a declarative manner.

import numpy as np

# Add weights to nodes and edges
for n in G.nodes():
    G.nodes[n]['weight'] = np.random.randn()

for e in G.edges():
    G.edges[e]['weight'] = np.random.uniform(1, 10)

# Draw the graph using Altair
viz = nxa.draw_networkx(
    G, pos=pos,

# Show it as an interactive plot!


To install from PyPI:

pip install nx_altair

To install for development, clone this repos and install using pip

pip install -e .

Todo list

A list of things to-do (good ideas for PRs).

  • Add draw method that mirrors networkx (easy)
  • Node color scale vmix, vmax (easy)
  • Edge color scale vmix, vmax (easy)
  • Node labels (medium)
  • Edge labels (medium)
  • Mouse-hover interactivity (medium)
  • Arrows for edges (hard)
  • Support for large (>1000 edge) networks (hard)
  • Force-directed interactivity (very hard---beyond altair's current support).
