<｜begin▁of▁sentence｜>### Instruction:
As an Information Security Analyst responsible for safeguarding computer systems and data from cyber threats, you have been tasked with visualizing a network graph in Gephi for analysis purposes. The network graph in question represents a tree structure with 10 nodes, where each internal node has 2 children. You are looking to stream an igraph object to Gephi using the GephiGraphStreamer API in Python to facilitate visual representation and further analysis of the network graph.
### Response:
import igraph as ig
import json
from igraph import GephiGraphStreamer

g = ig.Graph.Tree(10, 2)  # Create a sample tree graph

# GephiGraphStreamer usage example
streamer = GephiGraphStreamer()
json_event = next(streamer.iterjsonobj(g))
json_str = json.dumps(json_event)  # Convert the Python object to a JSON string

# Assuming we have a file-like object for Gephi,
# typically you'd have a network connection here
with open('gephi_stream.json', 'w') as file:
    streamer.post(g, destination=file)  # Post the graph to the file
