The International Consortium of Investigative Journalists used Neo4j to analyze connections in the Panama Papers. The ICIJ initially released CSV files, which can be loaded into Neo4j using tools like `neo4j-import` or on the command-line interface. Additionally, a bundled Neo4j database with the data is now available for download from their website. A video demonstrates how to get started with the Mac distribution, and a Docker image is also available for running the investigation. The ICIJ has released more information about their use of Neo4j in the Panama Papers investigation, which can be found on their website. Those new to Neo4j can access a free copy of the Learning Neo4j ebook to get started with the graph database.
