<｜begin▁of▁sentence｜>### Instruction:
Suppose you are an orthopedic surgeon working in a hospital, and you have a patient with a complex fracture. You need to visualize the fracture pattern and the relationship between different bone fragments to plan the surgical procedure effectively. How can you use Plotly to create a graph that represents the fracture pattern as a simple graph with edges labeled, and position the edge labels at the midpoint of each bone fragment?
### Response:
import igraph as ig
 import plotly.graph_objects as go

# Create a simple graph
edges = [(0, 1), (1, 2), (2, 3)]
g = ig.Graph(edges)

# Create positions
layout = g.layout('kk')

# Here we would have to implement a custom PlotlyEdgeDrawer to use get_label_position
# But for simplicity, we'll compute the midpoints directly
edge_midpoints = [(layout[edge[0]][0] + layout[edge[1]][0]) / 2,
                (layout[edge[0]][1] + layout[edge[1]][1]) / 2] for edge in edges]

# Create a Plotly trace for the edges
edge_trace = go.Scatter(x=[point[0] for point in edge_midpoints],
                        y=[point[1] for point in edge_midpoints],
                        text=['edge label' for _ in edges],
                        mode='markers+text',
                        marker=dict(size=10))

# Assuming here we would have used the get_label_position method to get more accurate positions

# Plot the graph
fig = go.Figure(data=[edge_trace])
fig.show()
