<｜begin▁of▁sentence｜>### Instruction:
{'description': 'Suppose we have two rooted trees: the first tree is a balanced binary tree with a depth of 3, and the second tree is a balanced tree where each node has 3 children and the tree has a depth of 2. How can we use NetworkX to join these two trees into a new single rooted tree?'}
### Response:
import networkx as nx

# Create several rooted trees
T1 = nx.balanced_tree(2, 3, create_using=nx.DiGraph)
T2 = nx.balanced_tree(3, 2, create_using=nx.DiGraph)

# Join the rooted trees with a new root
T = nx.join(T1, T2)

# Draw the joined tree (requires matplotlib)
nx.draw(T, with_labels=True)
