What Visualization Is For

This lesson defines what visualization is for: not decoration, but clear communication. Learners will see how visuals help people compare, spot patterns, remember key points, and make decisions faster than text alone. The lesson also distinguishes between visualizing data and visualizing ideas, so students can choose the right form for the communication goal.

By the end, learners will be able to explain the purpose of a visual, identify when a visual is useful, and avoid using charts, diagrams, or dashboards just because they look polished.
