#30DayChartChallenge, aka my not-quite-30 days Between juggling two projects, delivering training abroad, and being knocked out by illness, I had to choose my battles, and this challenge couldn’t be one of them. Still, I created work I’m proud of, even if some of it never saw the light of day. 1/4

This was my favourite #30DayChartChallenge plot and got me interested in what measles cases look like across the world. I've pulled the provisional data from the World Health Organisation and curated it for #TidyTuesday this week. Can't wait to see what you make! tidytues.day/2025/2025-06...

True—PM2.5 stats won't save your stir-fry. Air quality charts track pollution, not how much spice you're burning in the pan. Maybe we need an AQI for kitchens 😂 #30DayChartChallenge

What's the value of contributing to the #30DayChartChallenge ? I took a moment for self-reflection to think about that & put it into a new post on the blog www.gregdubrow.io/posts/l…. Thoughts on improving my #rstats & #dataviz skills, learning more about education in 🇩🇰 & lots more.. 1/

How worried are Europeans about climate change - and do they feel it's their job to help fix it? ♨️ Each dot represents a respondent's level of worries about climate change and their feeling of personal responsibility to address it. #30DayChartChallenge #Day15 Complicated 📊 #rstats.

24 scatterplots arranged in a small multiple grid, 1 plot per country in the ESS. They show how worried respondents are about climate change (x-axis, 1-5 scale) and how much they feel responsible to address it (y-axis, 0-10 scale).

Think nuns were just about prayer? Think again! This chart reveals the economic engines of the medieval monastic world, clustered by activity, source of wealth and colored by order. ✨💰 #30DayChartChallenge2025 Relationships | Clustera

#30DayChartChallenge - Day 30: National Geographic theme The final one! I had no idea what the style was so I Googled and found some interesting charts about tea from NatGeo which I used as inspiration. Not happy with the placement of the chart but I quite like the final result. #rstats #dataviz

#30DayChartChallenge - Day 29: Extraterrestrial I chuckled putting this one together for lots of reasons but especially because I loved E.T. as a kid. All data was from IMDB and after failing at scraping it, the {datapasta} was a lifesaver! #rstats #dataviz

E.T.
THE EXTRA-TERRESTRIAL
Where does E.T. rank among the movies listed on IMDB* as being directed by Steven Spielberg? Films are ranked by their IMDB rating below

#30DayChartChallenge - Day 28: Inclusion What's the opposite of inclusion? Exclusion and this chart compares the rate of adults at risk of poverty or social exclusion in the EU based on their country of birth. #rstats #dataviz

Adults at risk of poverty or social exclusion in the European Union
Percentage of the population aged 18 years and older at risk of poverty or social exclusion (AROPE) in 2024 based on whether their country of the birth is the same as their country of residence or is a foreign country. In all countries apart from Hungary the AROPE rate is higher for those born in a foreign country than for those born in the country of residence.
