<｜begin▁of▁sentence｜>### Instruction:
As an Information Security Analyst, you have been tasked with visualizing an Erdős–Rényi random graph with 10 vertices and a connection probability of 0.5 for a presentation on network security. You need to create a plot of the graph with a specific bounding box size of 300x300 pixels and save it to an image file named 'my_graph_plot.png' to include in your presentation. This will help illustrate a network model for academic or illustrative purposes.
### Response:
from igraph.drawing import Plot
from igraph import Graph

# Load a graph
graph = Graph.Erdos_Renyi(n=10, p=0.5)

# Create a plot with specific bbox size
plot = Plot(bbox=(300, 300))
plot.add(graph)

# Save the plot to a file
plot.save('my_graph_plot.png')
