networkx.drawing.layout.planar_layout¶

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

Position nodes without edge intersections.

Parameters

G (NetworkX graph or list of nodes) – A position will be assigned to every node in G. If G is of type PlanarEmbedding, the positions are selected accordingly.

Parameters
• G (NetworkX graph or list of nodes) – A position will be assigned to every node in G. If G is of type nx.PlanarEmbedding, the positions are selected accordingly.

• scale (number (default: 1)) – Scale factor for positions.

• center (array-like or None) – Coordinate pair around which to center the layout.

• dim (int) – Dimension of layout.

Returns

pos – A dictionary of positions keyed by node

Return type

dict

Raises

NetworkXException – If G is not planar

Examples

>>> G = nx.path_graph(4)
>>> pos = nx.planar_layout(G)
