dwave_networkx.drawing.zephyr_layout.draw_zephyr

draw_zephyr(G, **kwargs)[source]

Draws graph G in a Zephyr topology.

Parameters

  • G (NetworkX graph) – Zephyr graph or a subgraph of a Zephyr graph as produced by the dwave_networkx.zephyr_graph() function.

  • linear_biases (dict (optional, default {})) – Linear biases as a dict of the form {node: bias, ...}, where keys are nodes in G and biases are numeric. If specified, the linear biases are visualized on the plot.

  • quadratic_biases (dict (optional, default {})) – Quadratic biases as a dict of the form {edge: bias, ...}, where keys are edges in G and biases are numeric. Self-loop edges (i.e., \(i=j\)) are treated as linear biases. If specified, the quadratic biases are visualized on the plot.

  • kwargs (optional keywords) – Parameters in draw_networkx(), except for the pos parameter. If the linear_biases or quadratic_biases parameters are specified, the draw_networkx() node_color or edge_color parameters are ignored.

Examples

This example plots a Zephyr graph with size parameter 2.

>>> import networkx as nx
>>> import dwave_networkx as dnx
>>> import matplotlib.pyplot as plt   
>>> G = dnx.zephyr_graph(2)
>>> dnx.draw_zephyr(G)    
>>> plt.show()
