Which approach ensures all rows appear in a Python visual by modifying the data rather than the visual settings?

Which approach ensures all rows appear in a Python visual by modifying the data rather than the visual settings?

• A. Add a unique field to each row
• B. Turn off grouping in the visual
• C. Use a larger dataset size
• D. Apply a density filter

Answer: (A)

All rows appear when the data itself carries a distinct identity for every record. By adding a unique field to each row, you give every observation its own key, which prevents implicit aggregation or collapsing of rows that share other values. When the Python script receives a DataFrame with a unique identifier per row, it can plot every original row instead of only a summarized or grouped version. The other options don’t ensure every row is shown: turning off grouping changes how the visual presents data but can still rely on the data’s inherent granularity and may not prevent aggregation at the data level; using a larger dataset size doesn’t address aggregation or filtering; applying a density filter explicitly removes rows, reducing what you see.
