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:

nx.NetworkXException – If G is not planar

Examples

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