How can I create network graph from dataframe

Question

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?

Answer 1

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)
