<｜begin▁of▁sentence｜>### Instruction:
As an audio engineer, you receive a request to record and mix audio for a live concert event. One of the tasks includes generating a format compatible with Gephi's Graph Streaming API to visualize the network of audio signals at the concert venue. This specific request involves adding an edge with a weight attribute of 2.5, originating from the audio input labeled 'A' and terminating at the audio output labeled 'B'. Can you formulate the necessary event for the Graph Streaming API to add this edge to the Gephi graph visualization?
### Response:
from GephiGraphStreamingAPIFormat import GephiGraphStreamingAPIFormat

# Initialize the Gephi Graph Streaming API format helper
gs = GephiGraphStreamingAPIFormat()

# Generate an event to add an edge from vertex 'A' to vertex 'B' with an attribute
edge_event = gs.get_add_edge_event('A', 'B', True, {'weight': 2.5})

# Assuming you have a mechanism to send this to a Gephi server
print(edge_event)
