# AnnotationCollisionMode

Constants that indicate the collision mode for an annotation.

```
const AnnotationCollisionMode: Readonly<{
    readonly Rectangle: "rectangle";
    readonly Circle: "circle";
    readonly None: "none";
}>
type AnnotationCollisionMode =
    (typeof AnnotationCollisionMode)[keyof typeof AnnotationCollisionMode];
```

[`readonly Circle: "circle";`](/documentation/MapKitJS/AnnotationCollisionMode/Circle)
