<｜begin▁of▁sentence｜>### Instruction:
Given a new Plotly Graph Figure, how do you initialize the PlotlyGraphDrawer in igraph to draw vertices and edges onto the figure?
### Response:
import plotly.graph_objects as go
from igraph.drawing.plotly import PlotlyGraphDrawer

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

# Construct the graph drawer
drawer = PlotlyGraphDrawer(fig)

# Now you can use drawer to add vertices and edges to the figure
# Example: Add a single vertex
drawer.draw_vertices([(0, 0)])

# Example: Add an edge
drawer.draw_edges([((0, 0), (1, 1))])

# Display the figure
fig.show()
