New tools like graph databases allow data journalists to understand the intricate networks of the criminal, economic and political world better as those three examples show. Each journalist adding new connections helps others to validate their stories. They say "It's like magic".
Join Michael for a look behind the scenes of graph based data ingestion, analysis and investigation.
