<｜begin▁of▁sentence｜>### Instruction:
Given a binary tree graph with 127 vertices where each non-leaf vertex has exactly two children, can you generate and plot the corresponding dendrogram using the igraph VertexDendrogram with a 'left-right' orientation?
### Response:
import igraph as ig
import matplotlib.pyplot as plt

# Generate a simple graph and its VertexDendrogram
g = ig.Graph.Tree(127, 2)
dendrogram = g.community_edge_betweenness().as_clustering().as_dendrogram()

# Create a plot with specific orientation
fig, ax = plt.subplots()
dendrogram.__plot__(ax, orientation='left-right')

# Display the plot
plt.show()
