The neo4j-clojure wrapper library allows developers to interact with Neo4j, a graph database, using Clojure, a Lisp dialect running on the JVM. The library provides an interface for creating and managing nodes and relationships in the graph database. Using this library, developers can write code that looks similar to the example provided, which creates two new nodes and establishes a relationship between them. The wrapper library was announced and made available for use by developers interested in working with Neo4j.
