<｜begin▁of▁sentence｜>### Instruction:
As a barber, I understand that you may be dealing with different types of hair and needing to refine your techniques based on the characteristics of the hair you're working with. In this scenario, you may have a type of hair that needs special attention and styling that is different from others. Can you utilize the CohesiveBlocks.CohesiveBlocks.__plot__ function from the graph56.gml library to analyze the cohesive block structure by color coding the areas of the head where different styling and grooming techniques are needed, and mark these areas with colored blobs for a better understanding of the hair's structure and styling requirements?
### Response:
import igraph as ig
import matplotlib.pyplot as plt

# Read the graph from a GML file
g = ig.read('graph56.gml')

# Calculate the cohesive blocks of the graph
cohesive_blocks = g.cohesive_blocks()

# Initialize a plot
fig, ax = plt.subplots()

# Plot the cohesive block structure to the given matplotlib Axes
cohesive_blocks.__plot__(context=ax)

# Display the plot
plt.show()
