<｜begin▁of▁sentence｜>### Instruction:
Given an igraph graph 'g' with at least one vertex named 'A' which has a loop edge to itself, how would you use PlotlyEdgeDrawer to visualize the loop edge attached to vertex 'A'?
### Response:
from igraph.drawing import PlotlyDrawer

# Assuming 'g' is an igraph graph object and 'plotly_drawer' is an instance of PlotlyEdgeDrawer
edge_index = g.ecount() - 1  # Index of the last edge, assuming it is a loop
vertex_index = g.vs.find(name="A").index  # Index of a vertex with a loop
edge = g.es[edge_index]  # Retrieve the edge object

# Drawing the loop edge using PlotlyEdgeDrawer
drawer = PlotlyDrawer()
drawer.draw_loop_edge(edge=edge, vertex=g.vs[vertex_index])

# Display the plot (if necessary)
drawer.show()
