This week, we are learning how to set up Neo4j Sandbox for Summer of Nodes. The Neo4j Sandbox is a collaborative and interactive environment that allows users to invite team members and stay live for up to 10 days. It's particularly suited for new users who want to play around with a simple example, enabling them to jump into the code and interact with different guides via desktop or console. For those who are especially new to Neo4j, Sandbox provides an immersive experience that can be accessed on-demand.
