Meet Moritz Stefaner, a data designer who uses data for storytelling and who helped design the official German Covid-19 vaccine data dashboard. Moritz tells The Data Wranglers — Jeffrey Heer and Adam Wilson — how he creates a character from a dataset to give it emotional meaning and talks about the Covid vaccine clock he created. And, he dives into his data visualizations for train traffic on a German railroad network, the promises and pitfalls of using machine learning for data design, and what it took to visualize 175 years of text from Scientific American. Moritz hosts the popular podcast, Data Stories. #TheDataWranglers
