Tableau is a business intelligence and data visualization tool that allows users to make sense of their data through interactive charts, graphs, and diagrams. It has two main components: Tableau Desktop, which is used to connect to and analyze data and create visualizations, and Tableau Server, which is used to share insights and visualizations across an organization by controlling access. Tableau Desktop licenses cost $1,500 for the first year and $300 for subsequent years, while Tableau Server publisher licenses that allow uploading content to share cost $2,500 per year. Support is provided by Emory's LITS department.
