30 Day Chart Challenge

a chart-a-day gallery by Guillaume Noblet

Dear wanderer, welcome to my #30DayChartChallenge gallery!

Each chart you see here corresponds to a daily challenge of the #30DayChartChallenge. Some charts are most likely complete, while others are works in progress or placeholders for future creations.

I take the challenge as a learning and sharing time, exploring new techniques, tools, and datasets. Feel free to check the code behind each chart by clicking on the thumbnails.

🍂 Have fun, explore, and reuse!
