<｜begin▁of▁sentence｜>### Instruction:
As an animator creating visual content for a new video game, you receive a file named "example_graph.graphml" containing a graph structure representing a game level. Using the is_dag function in igraph, you need to determine if the graph represents a directed acyclic graph (DAG), which is crucial for ensuring proper level progression and avoiding any unintended loops or dead-ends in the game. After analyzing the graph, kindly print the result to indicate whether the game level graph is indeed a DAG or not.
### Response:
from igraph import Graph

# Load the graph from a file
graph = Graph.Read_GraphML('example_graph.graphml')

# Check if the graph is a DAG and print the result
is_dag = graph.is_dag()
print('Is the graph a DAG?', is_dag)
