This document discusses using Tableau with PowerPivot to create data visualizations. PowerPivot allows for scaling and empowering access to data through its column-oriented data store. Tableau's strengths are in data visualization and ease of use for business users. The key advantage is that business users can analyze their own data in PowerPivot and then visualize it using Tableau's best practices for data visualization without needing IT assistance. The document demonstrates recreating PowerPivot sample visualizations in Tableau to improve upon them.
