=== "VertexAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    vertex_annotator = sv.VertexAnnotator(
        color=sv.Color.GREEN,
        radius=10,
    )
    annotated_frame = vertex_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```

=== "EdgeAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    edge_annotator = sv.EdgeAnnotator(
        color=sv.Color.GREEN,
        thickness=5,
    )
    annotated_frame = edge_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```

    </div>

=== "VertexLabelAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    vertex_label_annotator = sv.VertexLabelAnnotator(
        color=sv.Color.GREEN,
        text_color=sv.Color.BLACK,
        border_radius=5,
    )
    annotated_frame = vertex_label_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```

=== "VertexEllipseAreaAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    area_annotator = sv.VertexEllipseAreaAnnotator(
        color=sv.Color.GREEN,
        sigma=2.0,
    )
    annotated_frame = area_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```

    `sv.VertexEllipseAnnotator` is a compatibility alias for `sv.VertexEllipseAreaAnnotator`.

=== "VertexEllipseOutlineAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    outline_annotator = sv.VertexEllipseOutlineAnnotator(
        color=sv.Color.GREEN,
        sigma=2.0,
        thickness=2,
    )
    annotated_frame = outline_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```

=== "VertexEllipseHaloAnnotator"

    ```python
    import supervision as sv

    image = ...
    key_points = sv.KeyPoints(...)

    halo_annotator = sv.VertexEllipseHaloAnnotator(
        color=sv.Color.GREEN,
        sigma=2.0,
    )
    annotated_frame = halo_annotator.annotate(
        scene=image.copy(),
        key_points=key_points,
    )
    ```
