<｜begin▁of▁sentence｜>### Instruction:
As a greenhouse grower, imagine you have a large greenhouse with different sections for various types of plants. You have an igraph.Graph instance that represents the structure of the greenhouse, with each node representing a section and the edges representing the connections between them. You want to obtain a summary of the hierarchical structure, including the number of individual plant sections and the connections between them. You also want to visualize the structure using an ASCII representation, if possible. How would you go about doing this using the igraph API?
### Response:
import igraph as ig

# Assume 'g' is an igraph.Graph instance with some hierarchy
dendrogram = g.community_edge_betweenness()
# Convert it into a dendrogram
# The following line is just for illustration; the graph 'g' should be pre-defined.
# dendrogram = ig.Graph.dendrogram(hierarchy)

# Get the summary of the dendrogram
summary = dendrogram.summary(verbosity=1, max_leaf_count=10)

# Print the summary
print(summary)
