<｜begin▁of▁sentence｜>### Instruction:
As an Adaptive Technology Specialist who assists individuals with disabilities in using technology to improve accessibility and independence, suppose you are working on a project involving visualizing a network structure of a communication system in a company. The network consists of a tree graph with 5 main components where each central component has exactly 2 subcomponents. To achieve this, you are required to use igraph's Cairo backend to create a visual representation of the tree graph and save it as an image file. How would you proceed in generating this visualization to effectively analyze the network structure?
### Response:
from igraph import Plot, Graph

# Create a simple graph
g = Graph.Tree(5, 2)

# Create a plot with Cairo backend
plot = Plot('/tmp/graph.png')
plot.add(g)

# Using the draw method from a drawer (which is referenced by plot)
plot.redraw()

# Saving the plot to a file
plot.save()
