Create a weighted graph based on Dataframe-CodePudding

consider a data frame like this:

id	source	Target	Weight
1	A	B	1
2	A	C	2
3	A	D	3
4	A	E	4

I want to depict a graph with networkX which shows us two things: 1-Node with more connections has a larger size, respectively. 2-Edge with more weight has a thicker line in between.

CodePudding user response：

We can set the edge_attr to Weight when we create the Graph

Setup Used:

import networkx as nx
import pandas as pd
from matplotlib import pyplot as plt

df = pd.DataFrame({
    'id': [1, 2, 3, 4],
    'source': ['A', 'A', 'A', 'A'],
    'Target': ['B', 'C', 'D', 'E'],
    'Weight': [1, 2, 3, 4]
})
