Every number needs context
Explainable data components
Charts become useful when people can understand the source, period, unit, uncertainty, comparison, and consequence. These components pair compact visuals with the text and controls required to make a responsible decision.
Why this set works
A stronger implementation baseline.
Units, periods, sources, and uncertainty stay attached to each value
Anomalies include a readable explanation and investigation path
Partial and stale data states remain visible before decisions are made

Implementation checklist.
Use these checks after adapting the components to your content and application state.
- 01
Name the source, unit, comparison period, and update time.
- 02
Explain confidence and missing data in language suited to the audience.
- 03
Provide a text or table equivalent for visual encodings.
- 04
Keep filtering controls from silently changing the meaning of a metric.
