+ * A specialized extension of {@link DatabaseManager} that provides access to a graph database represented by the
+ * {@link org.apache.tinkerpop.gremlin.structure.Graph} interface from Apache TinkerPop.
+ * <p>
+ * Implementations of this interface are expected to provide methods for interacting with the underlying graph
+ * database, such as retrieving vertices, edges, and properties, executing graph traversals, and performing other
+ * graph-related operations.
+ * <p>
+ * In addition to the functionality inherited from {@link DatabaseManager}, implementations of this interface
+ * also act as suppliers of the underlying {@link org.apache.tinkerpop.gremlin.structure.Graph} instance.
