This example is probably the most basic network chart you can realise.
A network chart is constituted by nodes. These nodes are interconnected by edges. So a basic format is a data frame where each line describes a connection.
Here we construct a data frame with 4 lines, describing the 4 connections of this plot! So if you have a csv file with your connections, load it and you are ready to visualise it!
Next step: customise the chart parameters!
# libraries
import pandas as pd
import numpy as np
import networkx as nx
import matplotlib.pyplot as plt
# Build a dataframe with 4 connections
df = pd.DataFrame({ 'from':['A', 'B', 'C','A'], 'to':['D', 'A', 'E','C']})
df
# Build your graph
G=nx.from_pandas_dataframe(df, 'from', 'to')
# Plot it
nx.draw(G, with_labels=True)
plt.show()
I get this error:
AttributeError: module ‘networkx’ has no attribute ‘from_pandas_dataframe’

G=nx.from_pandas_dataframe(df, ‘from’, ‘to’)
throws an error because it has been deprecated. Instead, use “nx.from_pandas_edgelist(df, ‘from’, ‘to’)
when i tried to run this code i am getting error:
AttributeError: module ‘networkx’ has no attribute ‘from_pandas_dataframe’
G=nx.from_pandas_edgelist(df, ‘from’, ‘to’)
