This visualization shows the parent-event relationships in a hierarchical data model, where each event must resolve to exactly one of four possible parent types: booking, stock change, repair, or missing. It demonstrates validation logic that raises exceptions when zero or multiple parents are found, ensuring data integrity in the event structure. The code uses Python’s `raise Exception` for error handling and list comprehensions to filter `None` values from the candidate parent list. The rendering approach is not visible in this snippet, which focuses solely on the data validation logic rather than visual output.
