<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from littleballoffur1.sparse6, how do you use the DiffusionTreeSampler to sample a subgraph that forms a diffusion tree with 10 nodes?
### Response:
import networkx as nx
from littleballoffur import DiffusionTreeSampler
G = nx.read_sparse6('littleballoffur1.sparse6')
sampler = DiffusionTreeSampler(number_of_nodes=10)
sampler_G = sampler.sample(G)
print(sampler_G.edges(), sampler_G.nodes())
