Dominik Moritz — Building Intuitive Data Visualization Tools
Gradient Dissent: Conversations on AI
Shownotes Transcript
Dominik shares the story and principles behind Vega and Vega-Lite, and explains how visualization and machine learning help each other.
Dominik is a co-author of Vega-Lite, a high-level visualization grammar for building interactive plots. He's also a professor at the Human-Computer Interaction Institute Institute at Carnegie Mellon University and an ML researcher at Apple.
