<｜begin▁of▁sentence｜>### Instruction:
As an astronomer, you have been studying a particular region of the night sky known for its unique cluster of stars. With the data collected from your observatory, you have saved a file named 'star_cluster_graph.pkl' containing a pickled version of a graph representing the connections between stars in this cluster. Could you use the networkx library in Python to read this graph and provide a summary of its properties so that we can better understand the relationships within the star cluster?
### Response:
from igraph import Graph

# Read the graph from a pickle file
pickle_file = 'graph_pickle.pkl'
g = Graph.Read_Pickle(pickle_file)

# Output the summary of the graph
g.summary()
