As digital platforms become more complex, journalists no longer simply ask themselves how best to portray a story with words and pictures. The digital medium provides unique and dynamic opportunities for stories and data to come to life. Data visualization — graphs, animations, interactives, and more — is increasingly becoming one more tool in a journalist’s storytelling kit. This week, we’ll be joined by Len de Groot, the new director of data visualization at the Los Angeles Times, to discuss how media outlets are pushing the limits of visual storytelling. We’ll also take a more philosophical turn on this episode and discuss the tricky issue of defining a journalist, especially in the context of penning shield laws that protect journalists from identifying their sources. To make sense of that debate, we’ll be joined by MediaShift contributors Jonathan Peters and Josh Stearns. We’ll also be joined by our regular panelist Andrew Lih of American University, new media consultant Sarah Evans, and our host Mark Glaser of MediaShift.
