We have come across several interesting data maps over the past few days, so this edition of DataViz Weekly leans spatial. The four projects we selected show how maps can make location, scale, and geographic patterns easier to explore. Today’s selection:
146 million U.S. jobs by sector — Kyle Walker
Sahel violence and Nigeria as its hotspot — The Guardian
Rio de Janeiro’s sister cities — Georgios Karamanis
A step line chart displays data as a continuous staircase, making it ideal for visualizing values that change at specific moments and hold constant in between. This tutorial walks through building one with JavaScript using ten years of U.S. Federal Funds Rate data, from a blank HTML page to a fully interactive step line chart ready to embed in any web page or application.
A new Friday, a new round of DataViz Weekly. We are here to share a small selection of data visualization projects that pulled us in lately and we believe will do the same for you. See what is in this edition:
Winners and losers on Polymarket — The Washington Post
Patterns in English similes — The Pudding
Big Tech lobbying in Germany — Zentrum für Digitalrechte und Demokratie
Data visualization does not take weeks off. We track charts and maps as they appear across the web and bring the most compelling finds together in DataViz Weekly. Our picks for this edition:
AI-generated content on the web — Jonas Dolezal, Sawood Alam, Mark Graham, and Maty Bohacek
Divorce rates by job — Nathan Yau
Global press freedom at a 25-year low — Reporters Without Borders
Every week, countless data visuals appear across all domains and formats. Every Friday, we curate those we found most interesting, sharing them as examples of data visualization work in practice. Glad to feature today in DataViz Weekly:
British voter intent by demographic — The Economist
America’s electrical grid under strain — The New York Times
Disappearance of iceberg A23a — The European Correspondent
There is always more to see when it comes to great charts and maps. Welcome to DataViz Weekly, where we put a spotlight on notable data visualizations as they come out around the web. Here are the projects that made the cut this time:
Tehran strike damage by land use — Bloomberg
Six decades of population change in Europe — Correctiv
Job stability across occupations in the United States — Nathan Yau
Robust data visualization makes complex subjects easier to see and understand. DataViz Weekly is our ongoing series collecting the best examples we come across most recently. Check out what stood out to us this week:
Causes of death across countries — Our World in Data
Good data graphics keep turning up online, and we never stop looking. DataViz Weekly is our regular roundup of the latest examples we think are worth your attention. Take a look at our new picks:
Early leaves and blooms across the United States — The Washington Post
D.C. cherry blossom shifts — Sara Staedicke
Satellites crowding Earth’s orbit — The Guardian
Every building in the Netherlands by year built — Bert Spaan
Traditionally, charts that visualize data over time are horizontal. But sometimes a vertical layout is a better fit. In this tutorial, you will learn how to create an interactive vertical area chart using JavaScript step by step.
The practical example uses monthly approval and disapproval ratings of American presidents from 1941 to 2025, according to Gallup polls. The final chart shows over 80 years of public support and opposition across U.S. administrations as two mirrored area series running top to bottom.
Data visualization has two core purposes: explanation and exploration. In DataViz Weekly, you can see how they naturally end up combining. Check out some of the most interesting data visualization examples we’ve found around the web lately, where charts and maps do their job in a compelling way:
China’s rise in AI research talent — The Economist
Shadow fleet capitalizing on the Iran war — The Financial Times
Vietnam’s rise as a U.S. electronics supplier — Bloomberg
Food self-sufficiency by country — Amanda Shendruk
