<｜begin▁of▁sentence｜>### Instruction:
As a product demonstrator, your task is to visually represent a new line of products at a trade show. You need to create a rectangular layout that showcases the products in a simple and orderly manner. The X-coordinate of each product corresponds to its position in the display, and you want to ensure that the rightmost product is positioned at the end of the rectangular layout. How would you approach setting the 'right' property of the rectangular display to the X-coordinate of the rightmost product plus one, using the NetworkX Graph API to organize the layout?
### Response:
import networkx as nx

# Create a simple graph
g = nx.Graph()
# Add edges to the graph
edges = [(0, 1), (1, 2), (2, 3)]
g.add_edges_from(edges)
# Assign the x-coordinate of the rightmost node in the graph (assuming horizontal layout with increasing X-coordinates)
rightmost_x = max(nx.get_node_attributes(g, 'pos').values(), key=lambda x: x[0])[0] if nx.get_node_attributes(g, 'pos') else None
# Create a representation of a rectangle including the graph
rectangle = {'left': 0, 'right': rightmost_x, 'top': 1, 'bottom': 0}
# Set the X coordinate of the right side of the box
rectangle['right'] = rightmost_x + 1

# Print updated rectangle
print(rectangle)
