Data Ink Priority

Data Ink Priority turns a frequent interface judgment into an executable constraint before generation.

Design Principle

Visual ink in charts and metrics should serve data, thresholds, and exceptions before decorative grids.

Principle

Visual ink in charts and metrics should serve data, thresholds, and exceptions before decorative grids.

Design action

Reduce grid and decoration; emphasize data marks, key points, thresholds, outlier labels, and current-state explanations.

Examples

Positive example: KPIs, trend charts, dashboards, and operational alerts need fast difference detection. Counterexample: Chart backgrounds, grids, and gradients are stronger than data marks.

Apply when

KPIs, trend charts, dashboards, and operational alerts need fast difference detection. Users need to judge state, scope, risk, or next action quickly.
