<｜begin▁of▁sentence｜>### Instruction:
Imagine you're advising a client on a personalized insurance policy and you need to graphically illustrate the decision flow. You've decided to create a diagram that shows the pathway, starting from the initial consultation and moving through various policy options. You want to visually represent this flow as a stepped pathway or graph, akin to what we see in NetworkX diagrams.

For your diagram, there are four critical stages in the policy selection process. You'd like to display this graphically, with the first stage standing alone as the starting point, and the subsequent stages grouped thereafter. This visual will be organized using what is referred to as a shell layout in NetworkX nomenclature.

Could you reorganize this information into a practical insurance-based scenario where the initial consultation is your starting node and forms the innermost shell, and the remaining stages—selecting policy options, customizing add-ons, and finalizing the premium—are in the outer shell, allowing for a clear and approachable visual for your client?
### Response:
import networkx as nx
import matplotlib.pyplot as plt

# Create a graph
G = nx.path_graph(4)

# Define shells
shells = [[0], [1, 2, 3]]

# Draw the graph using a shell layout
nx.draw_shell(G, nlist=shells)
plt.show()
