How can I create network graph from dataframe-CodePudding

I have dataframe like this table below:

source	destination	weight
A	B	0.5
A	C	0.2
B	C	0.1
B	D	0.1
C	D	0.1

How can I create network graph by source to destination and show number of weight on edge?

CodePudding user response：

You can import the data using

CodePudding user response：

import networkx as nx
import pandas as pd

data = {'source':["A", "A", "B", "B", "C"],
        'destination':["B", "C", "C", "D", "D"],
        'weight':[0.5, 0.2, 0.1, 0.1, 0.1]}

df = pd.DataFrame(data)

g = nx.Graph()

weighted_edges = list(zip(*[df[col] for col in df]))

g.add_weighted_edges_from(weighted_edges)
