<｜begin▁of▁sentence｜>### Instruction:
As a seasoned investigator, I have received a case involving a series of interconnected clues and evidence stored in a file named "tree_graph.gml". To unravel the mystery hidden within this file, I am tasked with utilizing a specialized algorithm called the Reingold-Tilford layout algorithm from the igraph's layout_reingold_tilford function. This algorithm will help me visualize the intricate relationships and structures present in the data, ultimately leading me closer to solving the case at hand.
### Response:
from igraph import Graph
import matplotlib.pyplot as plt

# Assuming 'g' is a tree or forest graph (e.g., read from 'tree_graph.gml')
g = Graph.Read_GML('tree_graph.gml')

# Apply the Reingold-Tilford layout algorithm
tree_layout = g.layout_reingold_tilford(mode='ALL')

# Draw the graph using the generated layout
fig, ax = plt.subplots()
plot = ig.plot(g, target=ax, layout=tree_layout, vertex_label=g.vs['name'])
plt.show()
