<｜begin▁of▁sentence｜>### Instruction:
As an aircraft mechanic, you may encounter the need to visualize complex networks of aircraft components and systems for better understanding and troubleshooting. Suppose you have a graph representing the connections between various aircraft components, and you want to visualize it as a dendrogram using the CairoDendrogramDrawer.draw function from the igraph library. Your aim is to create a PNG image with boolean style squares, grid width, and border width of 1, as well as labeled rows and columns, to aid in the analysis and decision-making process. This visual representation can help in identifying the relationships and dependencies between different aircraft components, ultimately supporting the maintenance and safety assurance processes.
### Response:
import igraph as ig
import cairo

# Create a Dendrogram
vertices = ['A', 'B', 'C', 'D']
edges = [(0, 1), (1, 2), (2, 3)]
graph = ig.Graph(edges=edges)
weights = [10, 20, 30]
dendrogram = graph.community_edge_betweenness(weights=weights).as_clustering()

# Initialize a Cairo surface to draw on
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 400, 400)
ctx = cairo.Context(surface)

# Create a DendrogramDrawer
drawer = ig.drawing.CairoDendrogramDrawer(dendrogram, ctx)

# Draw the dendrogram with desired options
drawer.draw(style='boolean', square=True, grid_width=1, border_width=1, row_names=vertices, col_names=vertices)

# Save to file
surface.write_to_png('dendrogram.png')
