D3.js Choropleth Map Code Walkthrough
Channel: Creating with Data
Date: 2023-07-03

Maps are some of the most shared and sought after forms of visualisation. For this second video, I walk through an example that visualises unemployment data at the US county level. The code was updated from this bl.ocks.org v4 example to use d3.js version 7.  The walkthrough touches on using d3-fetch to retrieve data on the web, as well as some basics of rendering geographic data.
