Dot and radial node layouts

Plot a tree or other directed, acyclic graph with the 'dot' or 'radial' node layout. Netgraph uses an implementation of the Sugiyama algorithm provided by the grandalf library (and thus does not require Graphviz to be installed).

import matplotlib.pyplot as plt
import networkx as nx

from netgraph import Graph

unbalanced_tree = [
    (0, 1),
    (0, 2),
    (0, 3),
    (0, 4),
    (0, 5),
    (2, 6),
    (3, 7),
    (3, 8),
    (4, 9),
    (4, 10),
    (4, 11),
    (5, 12),
    (5, 13),
    (5, 14),
    (5, 15)
]

balanced_tree = nx.balanced_tree(3, 3)

fig, (ax1, ax2) = plt.subplots(1, 2)
Graph(unbalanced_tree, node_layout='dot', ax=ax1)
Graph(balanced_tree, node_layout='radial', ax=ax2)
plt.show()
