Ritchie is a visual journalist at FiveThirtyEight, meaning he's a reporter who builds interactive data visualizations, makes and edits charts for the site, and does some writing here and there. He also makes tools that other members of the newsroom can use to, say, create their own charts. Before FiveThirtyEight, he worked at Quartz, Bloomberg Businessweek, and The New York Times and studied science journalism at NYU's Science, Health, and Environmental Reporting Program (SHERP). Ritchie is the author of Visual Storytelling with D3, a book that both introduces JavaScript’s excellent D3 library (which powers most web-based data visualizations) and touches on how to turn data into compelling visual stories.
