<｜begin▁of▁sentence｜>### Instruction:
As a speechwriter for a prominent tech company's CEO, you are tasked with preparing a speech about the company's network infrastructure enhancements and the use of networkx to optimize their processes. As part of the speech, you need to explain how to update the attributes of a specific edge in a graph. To illustrate this, consider a scenario where the CEO wants to highlight the importance of color coding in visualizing network connections. You can explain how, using networkx, the color attribute of an edge can be updated from 'blue' to 'red' to represent a critical link in the network.
### Response:
import networkx as nx

# Create a new graph
g = nx.Graph()

# Add an edge with additional attributes
e = (1, 2, {'weight': 4, 'color': 'blue'})
g.add_edge(*e[:2], **e[2])

# Update attributes of the edge
e_attrs = {'color': 'red'}  # New attributes to update
g[e[0]][e[1]].update(e_attrs)

# Print the edge attributes to verify the update
print(g[1][2])
