import networkx as nx
import nxviz as nv
G = nx.erdos_renyi_graph(n=20, p=0.3)

circ = nv.circos(G, node_color_by='key', sort_by='key')

由兩個子圖組成的圖，每個子圖內的節點彼此相連，但兩個子圖之間沒有連結。

import networkx as nx
G = nx.erdos_renyi_graph(n=100, p=0.03)

nx.connected_components(G)

<generator object connected_component_subgraphs at 0x10cb2c990>

list(nx.connected_components(G))

[<networkx.classes.graph.Graph at 0x10ca24588>,
 <networkx.classes.graph.Graph at 0x10ca244e0>]

for g in list(nx.connected_components(G)):
    print(len(g.nodes()))
