<｜begin▁of▁sentence｜>### Instruction:
Given a complete graph with 5 nodes, how would you set the top coordinate of the graph layout's bounding box to 100 and update the graph's visualization accordingly?
### Response:
from networkx.drawing.nx_agraph import to_agraph
import pygraphviz as pgv

# Create a NetworkX graph
g = nx.complete_graph(5)

# Convert to a PyGraphviz graph
agraph = to_agraph(g)

# Get the bounding box of the graph layout
bbox = agraph.get_bb()

# Set the top coordinate of the bounding box
bbox.top = 100.0

# Apply the new bounding box to the graph layout
agraph.set_bb(bbox)

# Draw the graph with the updated layout
agraph.draw('graph.png', prog='dot')
