<｜begin▁of▁sentence｜>### Instruction:
As a Book Editor, I review and prepare manuscripts for publication in book form. In a practical scenario, suppose I am tasked with reviewing a scholarly research book on network theory that includes a detailed study on an erdos_renyi_graph with parameters n=500 and p=0.4. The book mentions the utilization of the DiffusionSampler from the NetworkX library to sample a subgraph and identify the nodes sampled through a diffusion process. My role would involve ensuring that this process is accurately described, cohesive with the rest of the content, and effectively communicates the methodology to the readers.
### Response:
import networkx as nx
from littleballoffur import DiffusionSampler

G = nx.gnp_random_graph(n=500, p=0.4)

sampler = DiffusionSampler()

sampler_G = sampler.sample(G)

print(sampler_G.nodes())
