<｜begin▁of▁sentence｜>### Instruction:
In the healthcare field, imagine you're a respiratory therapist who is beginning to chart a new patient's history and proper treatment protocol in your database. Your approach is akin to how one might create an initial, empty patient chart, with no current records or treatments listed. The chart, in this case, represents a null graph using software like NetworkX—starting with a blank slate before any patient data (or in graph terms, nodes and edges) is introduced. Could you recast the process of initiating this empty patient chart, ensuring that it mirrors the steps for generating a clean graph structure, but now within the context of respiratory therapy? Remember, there are no gml files or specific data involved, as this is purely about setting the foundation for subsequent information.
### Response:
import networkx as nx

# Create a null graph with no nodes or edges
G = nx.null_graph()

# Display information about the graph
print(nx.info(G))
