<｜begin▁of▁sentence｜>### Instruction:
Given a triangle centered at (1, 1) and a line drawn from (0, 0) to (1, 1), where does the line intersect with the triangle if it were to be drawn using UpTriangleDrawer from the igraph library?
### Response:
import igraph as ig
import matplotlib.pyplot as plt
from igraph.drawing.matplotlib.uptriangledrawer import UpTriangleDrawer

# Create a Matplotlib figure and axis
fig, ax = plt.subplots()

# Instantiate the UpTriangleDrawer
drawer = UpTriangleDrawer(ax)

# Define the center of the triangle and the source point
(center_x, center_y) = (1, 1)
(source_x, source_y) = (0, 0)

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

# Optionally, you can draw the triangle and the line
# using normal matplotlib functions for visualization
ax.plot([source_x, center_x], [source_y, center_y], 'k-')
drawer.draw(center_x, center_y, 0.2)

# Set limits
ax.set_xlim(-1, 2)
ax.set_ylim(-1, 2)

# Show the plot
plt.show()
