The chart pages provide planning guidance in Phase 1. Data entry, rendering and exports are not implemented. A chart can communicate a pattern without establishing its cause.
Decisions before you begin
- Data values and labels
- Axis units or normalization
- Legend and visual encoding
Prepare the task
- Check the dataset for missing values and inconsistent units.
- Choose a chart form that answers the intended comparison.
- Review scales, labels and any aggregation before presenting the chart.
