<｜begin▁of▁sentence｜>### Instruction:
As a digital marketing specialist, I often need to analyze data to gain insights on customer behavior and preferences. Suppose you have a dataset that includes information on customer interactions and you're using Python with the NetworkX library to build a graph to visualize the connections between customers. How can you use NetworkX to add 5 new vertices (representing newly acquired customers) to an empty graph and then print a summary of the graph?
### Response:
import igraph as ig

# Create an empty graph
g = ig.Graph()

# Add 5 vertices to the graph
number_of_vertices_to_add = 5
g.add_vertices(number_of_vertices_to_add)

# Print the summary of the graph
print(g.summary())
