Data Visualization Tutorial: Mapping and Data Visualization of U.S. Migration Flows
This tutorial introduces the U.S. Census Bureau's Flows Mapper tool which maps the flow of people from one county to another using data from the 2006-2010 American Community Survey. Once the data is queried and downloaded from the site, the data is cleaned in MS Excel and visualized using Datawrapper's open source solution.
