Tableau Desktop is a free service that lets anyone publish interactive data visualizations to the web. Visualizations that have been published to Tableau Public (“vizzes”) can be embeded into webpages and blogs, they can be shared via social media or email, and they can be made available for download to other users.
Visualizations are created in the accompanying app Tableau Desktop Public edition (or another edition of Tableau Desktop) — no programming skills are required. Tableau Public is for anyone interested in understanding data and sharing those findings as data visualizations with the world. Journalists, writers, bloggers, students, professors, hobbyists, critics, citizens, and more. As soon as a workbook is published to Tableau Public, the viz is accessible by anyone on the internet.
