make_small_graph
(graph_description, create_using=None)[source]¶ Return the small graph described by graph_description.
graph_description is a list of the form [ltype,name,n,xlist]
Here ltype is one of “adjacencylist” or “edgelist”, name is the name of the graph and n the number of nodes. This constructs a graph of n nodes with integer labels 0,..,n-1.
If ltype=”adjacencylist” then xlist is an adjacency list with exactly n entries, in with the j’th entry (which can be empty) specifies the nodes connected to vertex j. e.g. the “square” graph C_4 can be obtained by
>>> G = nx.make_small_graph( ... ["adjacencylist", "C_4", 4, [[2, 4], [1, 3], [2, 4], [1, 3]]] ... )
or, since we do not need to add edges twice,
>>> G = nx.make_small_graph(["adjacencylist", "C_4", 4, [[2, 4], [3], [4], []]])
If ltype=”edgelist” then xlist is an edge list written as [[v1,w2],[v2,w2],…,[vk,wk]], where vj and wj integers in the range 1,..,n e.g. the “square” graph C_4 can be obtained by
>>> G = nx.make_small_graph( ... ["edgelist", "C_4", 4, [[1, 2], [3, 4], [2, 3], [4, 1]]] ... )
Use the create_using argument to choose the graph class/type.
