<｜begin▁of▁sentence｜>### Instruction:
Given a cycle graph with 4 nodes, how would you export the drawing of the graph to a LaTeX document, such that it can be compiled or included in a larger LaTeX project?
### Response:
import networkx as nx
import matplotlib.pyplot as plt

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

# Layout the graph
pos = nx.spring_layout(G)

# Draw the graph
nx.draw(G, pos)

# Export to LaTeX
nx.drawing.nx_pydot.write_dot(G, 'graph.dot')

# Assuming you have Graphviz and dot2tex installed:
# Convert the dot file to a LaTeX file
!dot2tex graph.dot > graph.tex

# Write the latex code to a file
with open('graph.tex', 'w') as f:
    latex_code = nx.drawing.nx_agraph.to_agraph(G).string()
    f.write(latex_code)

# Now you can include 'graph.tex' into your LaTeX documents
