It's almost time for the #30DayChartChallenge again!
As I start to plan out which days and prompts I'm going to do this year, I'm trying to implement my own advice from last year!
This year I'm going to focus on the CAPphrase dataset, because there's so many aspects of it I already want to dig into!
Dataset: https://github.com/adamkucharski/CAPphrase

Day 13/100: The year I became MapTheClouds ๐
2021 = transformative. #30DayMapChallenge + #30DayChartChallenge
Same year: launched https://maptheclouds.com, created brand/logo, refined COVID-19 network viz for Romania.
Lesson: discipline beats waiting for perfect conditions. Some days โ proud work. Others โ functional experiments. Both mattered. Showing up builds creative muscle memory.
End 2021: not just projects, but practice + platform + direction.
One of the things that has been on my to do list for a very long time, is building a gallery of all of the charts I've made across #TidyTuesday, #30DayChartChallenge, #30DayMapChallenge, and other miscellaneous projects ๐
And it's finally here!
I finally got around to writing up a โจ chart makeover โจ blog post based on my (deliberately) bad chart created for the #30DayChartChallenge! ๐
You can now see all my recent charts and their stories in 1 place: https://didoesdigital.com/30-day-chart-challenge-2025/

The 30 Day Chart Challenge is a data visualisation challenge where participants create a chart for each daily prompt. In this blog post, I'll recap the charts I made during the 2025 challenge and discuss the data and tools I used, alongside what I learned during the process.
