The Neo4j Data Importer has introduced an enhanced approach to improve the fidelity of its "Preview" feature, which allows users to visualize graph data before committing it to their database. This new feature validates the graph model, scans corresponding files for relationship and node data, and attaches relationships to loaded nodes. It also loads disconnected nodes, including solo nodes without fully mapped relationships or those with no matched rows in previous steps. The enhanced workflow improves preview accuracy by utilizing a single transaction instance of neo4j-driver and rolling back the operation after completion. This feature is now available for users to try out in their Neo4j Aura console, with a progress bar indicating the loading process's progress.
