<｜begin▁of▁sentence｜>### Instruction:
Given a graph and its community structure represented as a Cover object over the graph, can you use size_histogram to obtain the histogram of cluster sizes with a specific bin width?
### Response:
from igraph import Graph, Cover

# Assume 'g' is a Graph object and 'cover' is a Cover object over 'g'
g = Graph.Erdos_Renyi(n=100, p=0.05)
community = g.community_multilevel()
cover = Cover(g, community)

# Use size_histogram to get the histogram of cluster sizes
histogram = cover.size_histogram(bin_width=1)

# Print the sizes and their frequencies
for bin_range, count in zip(histogram._bin_ranges, histogram._bin_counts):
    print(f'Size: {bin_range}, Frequency: {count}')
