The dataset is a consumer complaints database from data.gov, containing over 2.3 million complaints about products from different companies. The Neo4j team re-enacts a popular webinar on loading CSV data into Neo4j using AuraDB Free, and imports the data into Neo4j to demonstrate its capabilities. The dataset includes nodes for Complaints, Companies, Products, SubProducts, Issues, SubIssues, Responses, and Tags, with relationships between them. The team demonstrates how to load and process the data, including filtering, merging, and querying the graph. They also provide examples of exploratory queries, such as finding sub-issues with communication tactics or typical response percentages per product. The dataset is available for exploration and analytics using Neo4j.
