As a nutritionist, you have been asked to create a visual representation of a meal plan graph for a group of 10 individuals. Each individual has two meal options to choose from. You need to use the 'generate_plot' function in MealPlanner software to generate and save a visual representation of the meal plan graph as a PNG file for easy reference.
### Response:
from igraph import Graph, plot

# Create a simple graph
g = Graph.Tree(10, 2)

# Plot the graph and save it to a file
g_plot = plot(g, target='tree_graph.png', bbox=(300, 300), margin=20)
