[denironyx]

Description:
Provide a simple use-case showcasing how to fetch BTS flight data (e.g. January 2024) and extract a manageable subgraph (e.g. 200 flights) for visualization/analysis.

For example:

• Build the full GraphFaker flight graph.
• Visualize the resulting subgraph and highlight delayed flights in red.
• Export to flight_sample.graphml.

Acceptance Criteria:

• A notebook or examples/flight_case_study.py script demonstrating:
