<｜begin▁of▁sentence｜>### Instruction:
Given a graph generated with the Erdős-Rényi model having 10 nodes and 15 edges, how would you dynamically change the bounding box of the plot from an initial size to 200x200 pixels before saving the resulting plot as 'graph_plot.png'?
### Response:
from igraph.drawing import Plot
from igraph import Graph

# Create a graph
g = Graph.Erdos_Renyi(n=10, m=15)

# Initialize a plot with specified bbox size
plot = Plot(bbox=(300, 300))

# Draw the graph on the plot
plot.add(g)

# Now let's change the bbox size of the plot dynamically
plot.coordinate_system.bbox = (200, 200)

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