Hey Maestro, Courses with your own 1:1 Maestro that knows the map.

The map connects each question to a skill and its prerequisites. For example, "my reviewer wants a pie chart. how do I explain why I chose bars?" connects to defending visualization decisions, which builds on critiquing a visualization and analyzing its audience.

Every course is written from ten years of data work in policy research and education. Your AI Maestro builds on what you’ve demonstrated, helps where you’re stuck, and guides your next step.
