Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Map view | Choose Map view when spatial relationship, proximity, coverage, route, region, or real-world placement changes the user's decision. | Markers, shapes, routes, clusters, and overlays represent explicit coordinates, features, or geographic areas, not decorative positions. | Google documents marker clustering for large marker sets and zoom-dependent cluster behavior. |
