<｜begin▁of▁sentence｜>### Instruction:
As a Materials Engineer working on optimizing materials for aerospace applications, imagine you're tasked with improving the structural integrity of aircraft components through advanced data visualization techniques. Your team decides to leverage Gephi's graph streaming API to analyze the relationships within a complex network of materials.

In this context, how would you structure a JSON event to incorporate a new material node, identified as 'n1', with attributes such as 'label' (set to 'Material 1') and 'attribute1' (set to 'value1') into the graph stored in Gephi?
### Response:
import json
from networkx.readwrite import json_graph

# Example usage to add a node with id 'n1' and attributes
node_id = 'n1'
attributes = {'label': 'Node 1', 'attribute1': 'value1'}
event = GephiGraphStreamingAPIFormat.get_add_node_event(node_id, **attributes)
json_event = json.dumps(event)

# The event is now ready to be sent to the Gephi graph streaming API
print(json_event)
