Explainable Labelled mini chart

Adds trend context to a compact value while retaining a textual explanation for trends, distributions, anomalies, and evidence; it is designed to pair every visual encoding with readable labels and interpretation. Point inspection updates an accessible caption and keyboard-selectable values. The charts and explainability variant is specialized for color and geometry cannot be the only carriers of meaning. Users can pair every visual encoding with readable labels and interpretation while understanding the current state, available choices, and resulting consequence.

Implementation field notes

Use explainable labelled mini chart confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Data visualization
  • Forecast
  • Adds trend context to a compact value while retaining a textual explanation for trends, distributions, anomalies, and evidence

This data visualization pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
  • Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
  • Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt primary signal, secondary signal, layered surface, primary text through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
