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

If you'd like to start playing with nx_altair, download this notebook!
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!
viz.interactive()
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,
node_color='weight',
cmap='viridis',
width='weight',
edge_color='black',
)
# Show it as an interactive plot!
viz.interactive()

If you have a feature request, please open an issue or submit a PR!
A list of things to-do (good ideas for PRs).
- Add
drawmethod 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).
