In April 2021, I decided to participate in #30DayChartChallenge , a data visualization challenge created by Cédric Scherer and Dominic Royé.

The challenge involved making one chart based on a specific week + day topic for 30 days, there was freedom to use whatever dataviz tools and data one liked.
My motivation and reason for participation was to strengthen my D3.js skills, therefore I decided to make one chart everyday with D3. Initially I published all my charts on ObservableHQ. Here's a link to my Observable collection. (opens new window)

This blog is created for the purpose of discussing the process of making each chart, code explanation for each chart and also to re-create the charts using basic HTML, CSS and D3.js.
