<｜begin▁of▁sentence｜>### Instruction:
Given the need to create a new graph with 3 vertices and connect these vertices with two edges, can you use the Graph.__new__ constructor in igraph to initialize the graph and add the necessary edges?
### Response:
from igraph import Graph

# Create a new graph with 3 vertices
n_vertices = 3
g = Graph(n_vertices)

# Add edges to the graph
g.add_edges([(0, 1), (1, 2)])

# Print the graph summary
g.summary()
