A visualized data generation device includes an acquisitor, an analyzer, and a generator. The acquisitor acquires manufacturing data including one or more pieces of first data Yi regarding a product state with respect to one product. The analyzer analyzes the first data Yi acquired by the acquisitor and derives a first index value with respect to each piece of the first data Yi. The generator generates visualized data including a first analysis result display region for causing a display device to display information about the first index value. The generator generates the visualized data in which an amount of information and a priority is set for each first analysis result display region on the basis of the first index value and a display form of the first analysis result display region is set on the basis of the amount of information and the priority.
