<｜begin▁of▁sentence｜>### Instruction:
As an organizational psychologist, imagine working with a team where the performance and communication among team members are crucial. You've been tasked with utilizing network analysis to determine the minimum number of team members that need to be removed to disrupt the flow of information and teamwork within the group. This will involve using the vertex_connectivity method from the igraph API to calculate the key vertices that, if removed, would lead to a disconnect in the communication and collaboration network.
### Response:
from igraph import Graph

# Create a graph instance
graph = Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 0), (0, 4), (4, 3)])

# Calculate the vertex connectivity of the entire graph
connectivity = graph.vertex_connectivity()

# Print the vertex connectivity
print('Vertex connectivity of the graph:', connectivity)
