<｜begin▁of▁sentence｜>### Instruction:
Given a diamond-shaped node centered at coordinates (0, 0), if there is a line drawn from a source point at (1, 1) to the center of the node, what are the coordinates of the intersection point between the perimeter of the diamond-shaped node and the line?
### Response:
from igraph.drawing import DiamondDrawer, plot
from igraph import Graph

g = Graph.Tree(3, 2)  # Creating a demo tree graph with 3 levels and 2 children per node
drawer = DiamondDrawer()
center_x, center_y = 0, 0  # Example center of the diamond
source_x, source_y = 1, 1  # Example source point

# Calculate the intersection point
intersection = drawer.intersection_point(center_x, center_y, source_x, source_y)
print('Intersection Point:', intersection)

# We can also create a plot to visualize
visual_style = {'vertex_shape': 'diamond'}
plot(g, **visual_style)
