Creating a graph from an edge list

We are going to be using this file as our original edge list: https://raw.githubusercontent.com/itsgorain/datasets/main/networks/alice/edgelist_alice_original.csv. Let’s take a look:

1. Before we can create our graph, we must import the two libraries we will be working with: pandas and networkx. We use pandas to read the edge list into a DataFrame, and we pass that DataFrame to networkx to create a graph. You can import both like so:

   import pandas as pd

   import networkx as nx

2. With the libraries imported, let’s use pandas to read the CSV file into a DataFrame and then display it, as shown in the following code block:

   data = 'https://raw.githubusercontent.com/itsgorain/datasets/main/networks/alice/edgelist_alice_original.csv'

   network_df = pd.read_csv(data)

   network_df.head()

If you run this in a Jupyter notebook, you should see the following DataFrame:
