Which type of logical data structure uses graphics to illustrate relationships among data elements?

Integration refers to the process of combining different systems or components to work together as a unified whole. While it may involve data, it does not specifically pertain to the graphical representation of relationships among data elements. Therefore, integration does not fit the description of a logical data structure using graphics.

The relational database model organizes data into tables, where relationships are established through foreign and primary keys. Although it can be represented graphically using Entity-Relationship (ER) diagrams, the term itself refers more to the structure of the database rather than the graphical representation of relationships among data elements specifically.

Structured Query Language (SQL) is a programming language used for managing and querying relational databases. While SQL is crucial for interacting with data, it does not involve graphical representations of data relationships. Thus, it is not considered a type of logical data structure that employs graphics.
