Example

Temporal playback

Animates a month of seeded synthetic seismic events with createTemporalPlayback, styled by a first-class classBreaksRenderer whose legend derives from renderer.legendItems().

Capabilities

Real-Time Feature Streams (streaming.feature-subscriptions)

Support tier: experimental Track: recipe Protocols: maplibre-geojson Renderers: maplibre Lifecycle: active — Canonical demo for first-class renderer objects + temporal playback (#497): renderer-driven styling, legend contracts, and filter-composed time windows. Qualification: experimental

Provenance & evidence

Runnable bytes and inline source are bound to producer commit 8f9d6a4fcde9aa78582fb12395ea5b9ef6d9f964.
Fixture lane: fixture / executed. Synthetic seismic events generated in the browser from a seeded PRNG; no network access.
Live lane: unavailable / not-applicable.
Expected degradation: Playback filters compose with bind-time layer filters; when MapLibre is unavailable the renderer objects still serialize and expose legend metadata headlessly.
2 explicit coverage gap(s) declared by the producer
- ./realtime (experimental): Only experimental catalog samples map to this supported SDK cell.
- realtime-facade (experimental): Only experimental catalog samples map to this supported SDK cell.
