Data Vis Dispatch, April 30

The best of last week’s big and small data visualizations

Welcome back to the 140th edition of Data Vis Dispatch! Every week, we publish a collection of the best small and large data visualizations we find, especially from news organizations — to celebrate data journalism, data visualization, simple charts, elaborate maps, and their creators.

Recurring topics this week include student protests, elections, borders, and things we do in our free time.

A great #30DayChartChallenge is coming to an end. Here’s what we liked from the fourth week of the challenge:

Nadya Andrianova: “Day 14 of #30daychartchallenge. Heatmap. Each rhombus shows number of people living in countries with different air quality levels. To show pollution level I used masks that still have since covid. More layers of fabric — lower air quality. Again you need light to see my viz 🌞,” April 28 (Tweet)
Joseph Ricafort: “Day 24: ILO Region for Africa (Data day) of #30DayChartChallenge. One of the challenges of working with a #dataset is the lack of consistency. Here’s a stepped area chart (including some abrupt changes in values) of #employment by #education levels across African countries,” April 27 (Tweet)
Ansgar Wolsing: “Truck mileage as an early indicator for the development of industrial production in Germany. 🚛
#30DayChartChallenge | #Day28 | Trend #rstats 📊 #ggplot2,” April 28 (Bluesky)
Steven Ponce: “2024 #30DayChartChallenge | day 24 | timeseries | ILO Africa Region (data day). The data comes from the ILO Africa region. This #viz compares the estimated working poverty rates by gender and age groups. 📂:… #rstats | #dataviz | #rstats | #ggplot2,” April 24 (Tweet)

Thousands of students have participated in pro-Palestinian protests at several U.S. colleges, leading to controversial arrests this week:

As you probably know, it’s election year… everywhere. Many newsrooms have already published U.S. election poll trackers and forecasts (The Economist, The Hill, The New York Times, The Wall Street Journal, and others). Reuters warns us that there’s often little to read into them:

And continuing with elections, here’s India (now the world’s most populous country!), Mexico, and some concerning polls from Germany:
