[gauge-activity-rings] Activity Rings Progress Chart

[MarkusNeusinger]

New plot type request.

Concentric radial progress rings showing goal completion for multiple metrics (e.g. daily move/exercise/stand or calories/minutes/steps), in the style popularized by fitness trackers: each ring is a partial arc with rounded caps, filled proportionally to goal completion, with distinct colors per metric and optional center labels.

Why: iconic, instantly recognizable chart type; fills the general radial-progress gap in the catalog (gauge-basic is a needle gauge, polar-bar is something else). Fully static-renderable in all libraries.

✅ Spec ID: gauge-activity-rings

Rationale: Grouped with the existing gauge-basic radial-progress family while activity-rings captures the distinctive concentric-arc variant popularized by fitness trackers.

This is a valid, useful chart type and not a duplicate — gauge-basic is a needle dial, polar-bar plots bars in polar coordinates, and donut-nested lacks the partial-arc/goal-completion semantics. No existing spec covers concentric radial progress rings. Fully static-renderable across all libraries.
