Tableau Public is a free service that lets anyone publish interactive data to the web. Once on the web, anyone can interact with the data, download it, or create their own visualizations of it. No programming skills are required. Windows is required for the desktop application.
The free version of Tableau Public is for writers, bloggers, students, professors, hobbyists, journeymen, critics, citizens and more. It’s also meant for organizations, but only as an introductory service, and for continued use requires commercial licensing.
