draw_spectral(G, **kwargs)[source]#

Draw the graph G with a spectral 2D layout.

This is a convenience function equivalent to:

nx.draw(G, pos=nx.spectral_layout(G), **kwargs)

For more information about how node positions are determined, see spectral_layout.

The layout is computed each time this function is called. For repeated drawing it is much more efficient to call spectral_layout directly and reuse the result:

>>> G = nx.complete_graph(5)
>>> pos = nx.spectral_layout(G)
>>> nx.draw(G, pos=pos)  # Draw the original graph
>>> # Draw a subgraph, reusing the same node positions
>>> nx.draw(G.subgraph([0, 1, 2]), pos=pos, node_color="red")


>>> G = nx.path_graph(5)
>>> nx.draw_spectral(G)
