What is Tableau?

Tableau is a data visualization platform that enables users to explore and communicate data effectively through interactive charts, dashboards, and maps. It’s widely used across many fields, including business, public policy, and research.

Tableau Public vs. Tableau Desktop

There are two main versions of Tableau:

  • Tableau Public is a free version that lets you create visualizations and publish them to a public web profile. It’s ideal for learning, sharing, and non-sensitive data.
  • Tableau Desktop is the full version available through paid licenses or free academic access for students. It includes additional features like saving locally and connecting to a broader range of data sources.
