PropertyGraph using Neo4j

In this notebook we will demonstrate building PropertyGraph using Neo4j

Neo4j is a production-grade graph database that excels in storing property graphs, performing vector searches, filtering, and more.

The simplest way to begin is by using a cloud-hosted instance through Neo4j Aura. However, for the purposes of this notebook, we will focus on how to run the database locally using Docker.
