<｜begin▁of▁sentence｜>### Instruction:
As an electrician, you are responsible for ensuring that electrical systems are operating effectively and safely. Imagine you are working on a project to visualize a complex electrical diagram using a graph representation. You have a list of specific electrical components and their connections, which are represented as a directed graph. To effectively represent differences in the characteristics of the connections, you need to set the arrow width for each edge based on a list of widths corresponding to the connections in the graph. Using the NetworkX library in Python, you want to achieve this by customizing the arrow widths on the edges to accurately reflect the variations in characteristics of the electrical connections.
### Response:
from igraph import Graph

# Sample graph creation
g = Graph([(0, 1), (1, 2), (2, 0)])

# Convert graph to directed so that setting arrow widths makes sense
g.to_directed()

# Visualize the graph before setting arrow width
g.vs['label'] = range(g.vcount())
plot_before = ig.plot(g, target='before_arrow_width.png', bbox=(300, 300))
plot_before.show()

# Set the arrow width to a uniform width
uniform_width = 2
plot_after = ig.plot(g, target='after_uniform_arrow_width.png', arrow_size=uniform_width, bbox=(300, 300))
plot_after.show()

# Set individual arrow widths
widths = [1, 2, 3]
for e, width in zip(g.es, widths):
    e['width'] = width
plot_after_individual = ig.plot(g, target='after_individual_arrow_width.png', edge_width=[e['width'] for e in g.es], bbox=(300, 300))
plot_after_individual.show()
