<｜begin▁of▁sentence｜>### Instruction:
As a licensed professional counselor, you may be working with a couple who are looking to improve their communication skills and strengthen their relationship. Imagine that you are using a tool that allows you to visually represent their communication patterns and connections as a graph. To help them understand the impact of their interactions, you need to update the weight of the edge connecting them to reflect the intensity of their communication. In this scenario, you can use the NetworkX API to create and manipulate the graph, enabling you to make the necessary changes and provide insights into their communication dynamics.
### Response:
from networkx.readwrite.json_graph import node_link_data
import json
from networkx import Graph

def change_edge_event(edge_id, attributes):
    # Simulate the function from GephiGraphStreamingAPIFormat
    event = {
        'an': {
            edge_id: attributes
        }
    }
    return json.dumps(event)

# Create a simple NetworkX graph
g = Graph()
g.add_edge(1, 2, weight=5.0)

# Change the edge attribute
edge_changes = {'weight': 3.0}

# Generate the change edge event JSON
edge_event_json = change_edge_event((1, 2), edge_changes)
print(edge_event_json)
