<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from a GML file, can you use the `cluster_graph` function of the `VertexClustering` class in igraph to combine clusters into a new graph? Each cluster is contracted into a single vertex, and vertices are connected if there was at least one connected vertex pair in the original clusters. Attributes of the vertices and edges of the new graph are derived using specified methods.
### Response:
from igraph import Graph, VertexClustering

# Load a graph from a file
g = Graph.Read_GML('path/to/your/graph.gml')

# Perform some clustering algorithm, e.g., community_multilevel
clustering = g.community_multilevel()

# Contract the clusters into a new graph
clustered_graph = clustering.cluster_graph(combine_vertices='mean', combine_edges=True)

# Print the summary of the clustered graph
print(clustered_graph.summary())
