circular_layout#

circular_layout(G, scale=1, center=None, dim=2)[source]#

Position nodes on a circle.

Parameters:
GNetworkX graph or list of nodes

A position will be assigned to every node in G.

scalenumber (default: 1)

Scale factor for positions.

centerarray-like or None

Coordinate pair around which to center the layout.

dimint

Dimension of layout. If dim>2, the remaining dimensions are set to zero in the returned positions. If dim<2, a ValueError is raised.

Returns:
posdict

A dictionary of positions keyed by node

Raises:
ValueError

If dim < 2

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.circular_layout(G)
