IPython Interactive Computing and Visualization Cookbook - Second Edition

Drawing flight routes with NetworkX

In this recipe, we load and visualize a dataset containing many flight routes and airports around the world (obtained from the OpenFlights website at https://openflights.org/data.html).

Getting ready

To draw the graph on a map, you need Cartopy, available at http://scitools.org.uk/cartopy/. You can install it with conda install -c conda-forge cartopy.

How to do it...

1. Let's import a few packages:

   >>> import math
       import json
       import numpy as np
       import pandas as pd
       import networkx as nx
       import cartopy.crs as ccrs
       import matplotlib.pyplot as plt
       from IPython.display import Image
       %matplotlib inline

2. We load the first dataset containing many flight routes:

   >>> names = ('airline,airline_id,' 'source,source_id,' 'dest,dest_id,' ...
