<｜begin▁of▁sentence｜>### Instruction:
Imagine we're composing a visual symphony—a graphical representation of a tight-knit jazz quartet, using the medium of a network graph. Our ensemble features four key players, nodes 0 to 3, harmoniously linked in what we call a path graph. Now, our leading player, node 0, deserves the spotlight, the center stage if you will, while nodes 1, 2, and 3 should fan out in the surrounding space like backup musicians.

We want to create a visual layout that captures this arrangement, not unlike arranging musicians on a stage. Using NetworkX's shell_layout as our stage director, how can we tactfully place our lead node 0 solo in the inner circle and let the other three nodes groove around in the outer shell? We're looking for a setup that's scaled just right (factor of 1), centered around the heart of our stage (the origin), without any fancy spins or rotations between our shells—that's not our style. Can you set the scene for this graphical jazz number?
### Response:
import networkx as nx
import matplotlib.pyplot as plt

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

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

# Generate the shell layout positions
pos = nx.shell_layout(G, nlist=shells, scale=1, center=(0, 0), rotate=0)

# Draw the graph using the shell layout
nx.draw(G, pos, with_labels=True)
plt.show()
