<｜begin▁of▁sentence｜>### Instruction:
Using NetworkX, how can you generate an unlabeled rooted tree with a specific number of nodes, and how do you identify the root of the tree? The code example demonstrates this for a tree with 5 nodes.
### Response:
import networkx as nx

# Generate an unlabeled rooted tree with 5 nodes
random_tree = nx.random_tree(n=5, seed=42)

# Access the root of the tree
root = random_tree.graph['root']

print(f'The root of the tree is: {root}')
print(f'The edges of the tree are: {random_tree.edges()}')
