EXP_008 /DATA VISUALIZATION LOGIC.
THESIS. A chart is an argument. Choosing the form from the question being asked, not the data available, makes visualizations that answer instead of decorate.
STATUSTESTING
01METHOD / OBJECTIVE
- Start from the decision each chart supports.

- Remove every mark that doesn't change the answer.
