<｜begin▁of▁sentence｜>### Instruction:
Imagine you're managing a network of rising stars, each with connections to different influential figures in the entertainment industry. You've created a diagram to visualize these connections: edges representing the relationships have been drawn between the up-and-coming talent 1 and industry insiders 2, 3, and 4, as well as between insider 3 and talents 4 and 5, and finally between insider 4 and talent 5.

In this bustling network that you've mapped out, who would be considered the key insiders—the ones at the very heart of this network—who provide the most direct line of communication to all the other members? These central figures are the ones you'd likely focus on to maximize the opportunities for all of your clients.
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add edges to the graph
G.add_edges_from([(1, 2), (1, 3), (1, 4), (3, 4), (3, 5), (4, 5)])

# Find the center of the graph
graph_center = list(nx.center(G))

# Print the center of the graph
print(f'The center of the graph is: {graph_center}')
