<｜begin▁of▁sentence｜>### Instruction:
Given 100 vertices and a graph generated using the forest fire model with a forward burning probability of 0.5 and a backward burning ratio of 0.7, how can you use igraph to create the graph and print a summary of it?
### Response:
import igraph as ig

# Parameters for the forest fire model
n = 100  # Number of vertices
fw_prob = 0.5  # Forward burning probability
bw_factor = 0.7  # Backward burning ratio

# Generate the graph
g = ig.Graph.Forest_Fire(n, fw_prob, bw_factor)

# Print summary of the graph
print(g.summary())
