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.
Learn with Sergio and your own AI Maestro. It builds on what you’ve demonstrated, helps where you’re stuck, and guides your next step.
