The Neo4j Stack Overflow Sandbox is a new resource that allows users to analyze Stack Overflow questions, answers, tags, and users with the help of Neo4j APOC and Graph Data Science. This sandbox provides an interactive browser guide to get started with social network analysis without requiring a Neo4j environment setup or ETL process. The sandbox offers a 3-day trial period that can be extended up to 10 days. Users can explore data using Cypher query language, Load JSON, APOC, and Graph Data Science algorithms to create virtual graphs and compare tags. This resource is part of the Neo4j Developer Blog on Medium, with additional resources available for further learning.
