<｜begin▁of▁sentence｜>### Instruction:
As a software architect designing the high-level structure of software systems and applications, imagine you're tasked with creating a visualization tool for analyzing hierarchical data within a network. Consider a scenario where you're developing a social network analysis tool for a marketing team. They want to visualize the hierarchical relationships between employees within different departments.

Now, suppose you have a dataset representing the organizational hierarchy of a company with 10 departments. Each department has a manager, and each manager oversees two sub-departments. Your task is to use the PlotlyGraphDrawer API from igraph to visually render and display this hierarchical tree graph.
### Response:
import igraph as ig
from igraph.drawing import PlotlyGraphDrawer
import plotly.graph_objects as go

# Create an example graph
g = ig.Graph.Tree(10, 2)

# Create a Plotly figure
drawer_fig = go.Figure()

# Create a PlotlyGraphDrawer and draw the graph
drawer = PlotlyGraphDrawer(drawer_fig)
drawer.draw(g)

# Show the Plotly figure with the graph
drawer_fig.show()
