Working with Graph Objects - Network Analysis in Python

This includes the basics of NetworkX and how to work with its specialized Graph objects. It uses the Marvel network data as an example.

Importing a Graph object¶

# Import NetworkX and key data science libraries
import networkx as nx
import pandas as pd
import numpy as np
import altair as alt

NetworkX provides lots of different functions for importing and exporting network data. Here we’ll go over the three you will most commonly encounter.

Network data is often stored in edge lists, plaintext files where every row contains a pair of nodes, separated by whitespace. Sometimes these files also include edge weights.

NetworkX has a read_edgelist() function for these kinds of files. If your file has a third column for weights, you can use read_weighted_edgelist().

# Import an edgelist of high school student interaction data.
HS = nx.read_weighted_edgelist("../data/contact-high-school-proj-graph.txt")
print(HS)

Graph with 327 nodes and 5818 edges

You can also use NetworkX read .gml files, which record network data using the Graph Modelling Language.

# Import a gml of college football data.
F = nx.read_gml("../data/football.gml")
print(F)

Graph with 115 nodes and 613 edges

Finally, you’ll also encounter edge list data in CSV files, where the node pairs are separated by commas instead of whitespace. In this cases, it’s often easier to use Pandas as an intermediary.

First, read the CSV with Pandas.

# Import a CSV of Marvel character co-occurrences.
marvel = pd.read_csv("../data/marvel-unimodal-edges.csv")
marvel

Then, convert the Pandas DataFrame into a NetworkX Graph object.

M = nx.from_pandas_edgelist(marvel, source="Source", target="Target", edge_attr=True)
print(M)

Graph with 327 nodes and 9891 edges

Graph objects include many different methods and properities. As you can see above, running print() on a Graph object will quickly tell you the number of nodes and edges.

Understanding Graph Objects¶

A graph object is essentially a set of nested Python dictionaries. You can access the dictionaries for nodes and edges with those respective properties.

# Get all nodes
M.nodes()

# Display just the first 10
list(M.nodes())[:10]

["Black Panther / T'chal",
 'Loki [asgardian]',
 'Mantis / ? Brandt',
 'Iceman / Robert Bobby',
 'Marvel Girl / Jean Grey',
 'Cyclops / Scott Summer',
 'Klaw / Ulysses Klaw',
 'Human Torch / Johnny S',
 'Richards, Franklin B',
 'Wolverine / Logan']

# Get all edges
M.edges()

# Display just the first 10
list(M.edges())[:10]

[("Black Panther / T'chal", 'Loki [asgardian]'),
 ("Black Panther / T'chal", 'Mantis / ? Brandt'),
 ("Black Panther / T'chal", 'Iceman / Robert Bobby'),
 ("Black Panther / T'chal", 'Marvel Girl / Jean Grey'),
 ("Black Panther / T'chal", 'Cyclops / Scott Summer'),
 ("Black Panther / T'chal", 'Klaw / Ulysses Klaw'),
 ("Black Panther / T'chal", 'Human Torch / Johnny S'),
 ("Black Panther / T'chal", 'Richards, Franklin B'),
 ("Black Panther / T'chal", 'Wolverine / Logan'),
 ("Black Panther / T'chal", 'Firebird / Bonita Juar')]

Nodes and edges can also have attributes, which are expressed as nested dictionaries within the node and edge lists. You can access them with the .data() property. In this case, the marvel network has an edge attribute named “Weight.”

# Get all edge data
M.edges.data()

# First 10 for display
list(M.edges.data())[:10]

[("Black Panther / T'chal", 'Loki [asgardian]', {'Weight': 10}),
 ("Black Panther / T'chal", 'Mantis / ? Brandt', {'Weight': 23}),
 ("Black Panther / T'chal", 'Iceman / Robert Bobby', {'Weight': 12}),
 ("Black Panther / T'chal", 'Marvel Girl / Jean Grey', {'Weight': 10}),
 ("Black Panther / T'chal", 'Cyclops / Scott Summer', {'Weight': 14}),
 ("Black Panther / T'chal", 'Klaw / Ulysses Klaw', {'Weight': 17}),
 ("Black Panther / T'chal", 'Human Torch / Johnny S', {'Weight': 44}),
 ("Black Panther / T'chal", 'Richards, Franklin B', {'Weight': 6}),
 ("Black Panther / T'chal", 'Wolverine / Logan', {'Weight': 9}),
 ("Black Panther / T'chal", 'Firebird / Bonita Juar', {'Weight': 7})]

Use Python dictionary bracket notation to access specific nodes or edges. Accessing a node or edge will return the dictionary that includes its attributes (if there are any).

# Accessing the node for the Marvel character Thanos
# This node has no attributes yet
M.nodes['Thanos']

{}

# Accessing the edge between Death and Thanos
M.edges[('Thanos','Death')]

{'Weight': 22}

# Or get the weight of an edge directly
M.edges[('Thanos','Death')]['Weight']

22

You can easily iterate through edges and nodes, accessing their attributes along the way.

# Iterating through nodes
for n in M.nodes():
    print(n)

Adding Attributes¶

You can add attributes to both nodes and edges in your Graph object. These attributes can come from outside sources, or they can be metrics you calculated inside NetworkX.

As an example, we can calculate node degree centrality and add it as an attribute.

# Calculate degree centrality for every node
# This returns a dictionary in the form we need
degree = nx.degree_centrality(M)
degree

Converting to Pandas DataFrames¶

Often you’ll need to convert your nodes or edges back into Pandas DataFrames in order to work with them statistically. Doing so for nodes and edges is very similar.

# Create a dataframe of nodes
nodes = pd.DataFrame.from_dict(M.nodes, orient='index')
# Reset the index to make all columns readable
# Depending on your version of NetworkX, this may not work the same way
nodes.reset_index(level=0,names="character",inplace=True)
nodes

# Create a dataframe of edges
edges = pd.DataFrame.from_dict(M.edges, orient='index')
# Reset the index to make all columns readable
# Depending on your version of NetworkX, this may not work the same way
edges.reset_index(names=["Source","Target"],inplace=True)
edges

Once you’ve converted your nodes or edges to a Pandas DataFrame, you can calculate common statistics, create visualizations, run machine learning models, and much more.

Now that you’ve learned the basics of Graph objects, you’re ready to move on to calculating metrics.
