<｜begin▁of▁sentence｜>### Instruction:
Imagine you're setting up for a thought-provoking documentary about the interconnectedness of various individuals in a community. You want to visually represent these connections with a simple graphic that follows a linear narrative, much like a path you'd set your camera on to unravel a story.

Your graphic has four main characters, each represented as a point in this narrative. You're looking to create a visual where the first character starts the story in its own spotlight, akin to placing them on a separate stage. The remaining three characters are part of the next chapter in this tale and thus share a common stage, a bit like grouping secondary interview subjects in one frame.

Let's say you're translating this concept using NetworkX for a storyboard, and you'd like to use the shell_layout to position these characters. How would you depict this arrangement, with the protagonist on their own and the rest sharing their part of the storyline?
### Response:
import networkx as nx
# Create a graph G
G = nx.path_graph(4)
# Define shells
shells = [[0], [1, 2, 3]]
# Use shell_layout to position nodes
pos = nx.shell_layout(G, shells)
print(pos)
