kamada_kawai_layout(G, dist=None, pos=None, weight='weight', scale=1, center=None, dim=2)¶
Position nodes using Kamada-Kawai path-length cost-function.
- GNetworkX graph or list of nodes
A position will be assigned to every node in G.
- distdict (default=None)
A two-level dictionary of optimal distances between nodes, indexed by source and destination node. If None, the distance is computed using shortest_path_length().
- posdict or None optional (default=None)
Initial positions for nodes as a dictionary with node as keys and values as a coordinate list or tuple. If None, then use circular_layout() for dim >= 2 and a linear layout for dim == 1.
- weightstring or None optional (default=’weight’)
The edge attribute that holds the numerical value used for the edge weight. If None, then all edge weights are 1.
- scalenumber (default: 1)
Scale factor for positions.
- centerarray-like or None
Coordinate pair around which to center the layout.
Dimension of layout.
A dictionary of positions keyed by node
