shell_layout¶
- shell_layout(G, nlist=None, dim=2, scale=1, center=None)[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.
- dim (int) – Dimension of layout, currently only dim=2 is supported
- scale (float) – Scale factor for positions
- center (array-like or None) – Coordinate pair around which to center the layout.
Returns: A dictionary of positions keyed by node
Return type: dict
Examples
>>> G = nx.path_graph(4) >>> shells = [[0], [1,2,3]] >>> pos = nx.shell_layout(G, shells)
This algorithm currently only works in two dimensions and does not try to minimize edge crossings.
