bfs_layout#

bfs_layout(G, start, *, align='vertical', scale=1, center=None)[source]#

Position nodes according to breadth-first search algorithm.

Parameters:
GNetworkX graph

A position will be assigned to every node in G.

startnode in G

Starting node for bfs

centerarray-like or None

Coordinate pair around which to center the layout.

Returns:
posdict

A dictionary of positions keyed by node.

Notes

This algorithm currently only works in two dimensions and does not try to minimize edge crossings.

Examples

>>> G = nx.path_graph(4)
>>> pos = nx.bfs_layout(G, 0)
