<｜begin▁of▁sentence｜>### Instruction:
As an ergonomist, imagine you are tasked with designing and evaluating a new control center for a transportation company. You have collected data on the network of communication channels among different divisions of the company. Now, you need to utilize the Cairo plotting capabilities in igraph to visualize the communication network graph, apply aesthetic attributes to different divisions, and then save the graph as an image for the proposal presentation.
### Response:
import igraph as ig

# Create a graph
g = ig.Graph([(0, 1), (0, 2), (2, 3), (3, 4)])

# Plot the graph using Cairo
visual_style = {}
visual_style['vertex_size'] = 20
visual_style['vertex_color'] = 'blue'
visual_style['vertex_label'] = g.vs['name']
visual_style['edge_width'] = 2
visual_style['layout'] = g.layout('kk')
ig.plot(g, 'mygraph.png', **visual_style)
