<｜begin▁of▁sentence｜>### Instruction:
In igraph, how would you generate a tree where each non-leaf vertex has a predefined exact number of children, for example 2, making it a binary tree, and with a given number of vertices, such as 10?
### Response:
from igraph import Graph

# Define the number of vertices and children for the tree
num_vertices = 10
children_per_vertex = 2

# Generate a tree
# In this example, every non-leaf vertex will have exactly 2 children
# which means it's a binary tree

# The argument `children` here stands for branching (how many children per vertex)
tree = Graph.Tree(n=num_vertices, children=children_per_vertex)

# Print the adjacency matrix to visualize the tree structure
print(tree.get_adjacency())
