networkx.shell_layout¶

networkx.shell_layout(G, nlist=None, scale=1, center=None, dim=2)[source]¶

Position nodes in concentric circles.

Parameters:	G : NetworkX graph or list of nodes nlist : list of lists List of node lists for each shell. scale : float Scale factor for positions center : array-like or None Coordinate pair around which to center the layout. dim : int Dimension of layout, currently only dim=2 is supported
Returns:	pos : dict 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)
>>> shells = [[0], [1, 2, 3]]
>>> pos = nx.shell_layout(G, shells)
