<｜begin▁of▁sentence｜>### Instruction:
If you need to generate an undirected graph with 4 vertices that corresponds to the 5th isomorphism class, how do you create and visualize this specific structure using igraph?
### Response:
import igraph as ig

# Number of vertices
n = 4

# Isomorphism class to generate; for 4 vertices, number of classes is 11 (0 to 10)
class_number = 5

# Generate the graph with the given isomorphism class
iso_class_graph = ig.Graph.Isoclass(n, class_number, directed=False)

# Plotting the graph
ig.plot(iso_class_graph, vertex_label=range(n))
