30 data visualisation stories

This April I participated in the 30DayChartChallenge and to make things interesting, after the first day, I've decided on combining this with my old dream of learning D3.js. This talk is about that journey, we will go through 30 data stories, how I found the data, sometimes collected it, charted it, and charted it again and again. Topics range from politics, to global warming and gender equality and ABBA.

Presented at ByteAdventures 2021
