<｜begin▁of▁sentence｜>### Instruction:
Given a tree graph with 5 vertices where each node has 2 children, how can you mirror the layout of the graph along the y-axis using Fruchterman-Reingold algorithm for visualisation?
### Response:
from igraph import Graph

# Create a simple graph
g = Graph.Tree(5, 2)  # Generate a tree with 5 vertices and children per node
layout = g.layout('fr')  # Use Fruchterman-Reingold layout

# Mirror the layout vertically (along the y-axis)
layout.mirror(dim=1)

g.plot(target='tree_mirrored.png', layout=layout, vertex_label=range(g.vcount()))
