<｜begin▁of▁sentence｜>### Instruction:
As a private investigator, you are tasked with conducting investigations to gather information and evidence in various fields. Imagine you have been hired to gather intelligence on a complex network of connections within a business or organization. You have received a graph representing these connections, with the edge set [(0, 1), (0, 2), (1, 2)]. Your client has requested that you use the Vertex.delete method in the networkx API to delete vertex 1 from the graph. Your task is to understand how to carry out this specific operation while maintaining the integrity of the network data.
### Response:
import igraph as ig

# Create a simple graph
g = ig.Graph([(0, 1), (0, 2), (1, 2)])

# Select a vertex to delete. Here, we delete vertex 1
vertex_to_delete = g.vs[1]

# Use the proxy method to delete the selected vertex from the graph
vertex_to_delete.delete()

print(g)
