Explore how different groups are likely to vote in the next British election (spoiler: there's been a huge shift to Labour) Had a lot of fun building this tool with @JamesFransham and @futuraprime #BuildABritishVoter economist.com/interactive/uk…

This was a fascinating dataset to work with: explore who dating app users say they're willing to date vs who they actually like. With @doug_dowson economist.com/graphic-detail…

One of those maps that you can get lost in. It uses satellite imagery originally designed to detect forest fires to map the extent of the war in Ukraine. With @Sondreus and @MatterofMatt economist.com/interactive/20…

There is no question about the bravery of Iranian protesters. But what is less clear is how widespread the protests are, if they are still growing - and how they might end. I looked at data on tens of thousands of events to find out (charts: @_rospearce ) economist.com/graphic-detail…

@AlbertoCairo @AlexSelbyB Nice work!

A draft of a map we didn't have space to include. It's interesting to see how the areas experiencing "very strong" or "extreme" heat stress have expanded north 🔴 New regions in 2017-22 compared with 1980-84

This map shows how many days of "very strong" or "extreme" heat stress each region had on average per year between 2017-22 #dataviz with @AinslieJstone economist.com/graphic-detail…

The distribution of humanity across the world is set to shift dramatically, according to the UN's population forecast. As China shrinks, India will continue to add citizens.

@bucknam I considered it but decided it looked fussy adding a halo to both. These connecting lines don't need to stand out as much. And yes it's best to avoid covering up the map below where possible

Nearly half of Mariupol's built-up area has been damaged 🔴 since the war began. This map is so detailed that editing it was almost too much for my laptop economist.com/graphic-detail…

@bwchen0719 @DataSciNews @TheEconomist Sure. We mainly use an in-house charting tool, ggplot, QGIS and Adobe Illustrator to tidy everything up

Most data comes with some uncertainty, yet it looks definitive when plotted on a chart. Making this uncertainty visible is one of the trickiest aspects of #dataviz I've written a brief intro to some of our approaches @TheEconomist in our data newsletter view.e.economist.com/?qs=47ab3ac6d3…

@gelliottmorris @TheEconomist Thanks!
