<｜begin▁of▁sentence｜>### Instruction:
As a fitness and nutrition consultant, you get a request from a new client who is a sports coach. They have a diamond-shaped training zone on their field, and they want to optimize the training route for their athletes. They need your help to determine the intersection point of a planned running track that starts from the (0, 0) point on the field and passes through the center of the diamond-shaped training zone at coordinates (1, 1). 
To achieve this, you believe GraphXAPI can be used to create a graph of the diamond shape and the running track, allowing you to identify the point of intersection for the most efficient training route.
### Response:
from igraph import Graph, plot
from igraph.drawing.shapes import DiamondDrawer

# Initialize a blank graph for demonstration
graph = Graph()

# Instantiate a DiamondDrawer
diamond_drawer = DiamondDrawer()

# Define center and source coordinates
center_x, center_y = (1, 1)
source_x, source_y = (0, 0)

# Get the intersection point
intersection = diamond_drawer.intersection_point(center_x, center_y, source_x, source_y)

# Output the intersection point
print(f'Intersection point: {intersection}')
