Accessible Visualization Authoring
Increasing accessibility to empower everyone to become creators of data visualizations.

View Data Model Enhancements
Be aware of how Tableau data models are used within a viz or worksheet, and which tables supply data to which pills in the viz. If a complex calculation is used within a pill, hovering over the pill highlights the participating tables in the View Data Model - confirming the logic's correctness. Diagnose and evaluate your analysis right in your flow of work, and avoid the swivel-chair process between worksheet and data source tabs.
