<｜begin▁of▁sentence｜>### Instruction:
As a Mediation Lawyer representing a technology company in a dispute over network infrastructure with a partner firm, I need to visualize the hierarchy of the network components shared between the parties. I would like to use the Graph.layout_reingold_tilford_circular method provided by the igraph API to compute and display a clear layout of the tree graph representing the network structure, indicating the relationship between the main components to aid in the negotiation process.
### Response:
from igraph import Graph

# Create a tree graph with edges forming a hierarchy
edges = [(0, 1), (0, 2), (1, 3), (1, 4), (2, 5), (2, 6)]
g = Graph(edges=edges)

# Compute the layout using Reingold-Tilford circular algorithm
layout = g.layout_reingold_tilford_circular()

# Plot the graph using the computed layout
ig.plot(g, layout=layout, vertex_label=g.vs.indices)
