How would you describe a visual check?

Explanation:
A visual check is manual inspection of data or outputs by looking at them to spot errors, inconsistencies, or formatting issues. It relies on human judgment to judge whether numbers, graphs, labels, and results look correct and plausible, catching problems that automatic checks might miss. It isn’t driven by a computer algorithm, and it isn’t a formal statistical test. This makes it a quick, intuitive quality-control step often used to verify presentation and obvious mistakes, though it can be subjective and not scalable for large datasets.
