Welcome to episode 8 of season 3 of Explore Explain, a long-form video and podcast series all about data visualisation design. In this episode I am delighted to welcome Ros Pearce, Visual Data Journalist at The Economist. We had a detailed conversation to explore the clever thinking behind an in-depth data study titled 'Nearly half of Mariupol has suffered grave damage' looking at the early phase of the Russian invasion of Ukraine, published in April 2022. As well as listening to this show, you can watch the video of this conversation, illuminated by accompanying visual details of the design workflow.
