The question asks: What is the visual representation of a data model called?

In database design and information systems, the standard visual depiction of a data model is an entity-relationship diagram (ERD). This type of diagram graphically shows entities (things about which we store information), their attributes (properties of those entities), and the relationships (how entities relate to one another). The ERD helps designers conceptualize and communicate the structure of a database before implementation.

Although the provided data does not list any answer choices, common alternatives that are not the correct fit for representing a data model include flowcharts (which illustrate processes and workflows), UML class diagrams (which model classes and their relationships in object-oriented design, not specifically a data model), and schema diagrams (which can be used for database structure but are not the conventional term for the data-model representation itself).

Without explicit options to compare, we can still align the concept with the recognized term: the visual representation of a data model is best described by an entity-relationship diagram, which captures entities, attributes, and relationships in a structured diagrammatic form.
