Mastering Tableau 2018.1, Second Edition 10.3: Dual Layer Mapping

The video tutorial covers the creation of dual layer maps using Tableau. It begins with an introduction to dual layer mapping, followed by steps to connect to the sample superstore dataset and create a base map of the United States. The tutorial then explains how to customize the base map by adjusting colors and density. It proceeds to demonstrate how to duplicate maps and merge layers to create a dual layer chart, visualizing profit and sales data. The video concludes with a preview of the next tutorial on custom geocoding.
