model = YOLO("yolov8n.pt") 
results = model("bus.jpg")
detections = sv.Detections.from_ultralytics(results[0])
frame = cv2.imread("bus.jpg")
annotated_frame = circle_annotator.annotate(
                scene=frame.copy(), 
                detections=detections, 
            )

cv2.imshow("frame", annotated_frame)
cv2.waitKey(0)

Hi, @onuralpszr 👋🏻! Would you be so kind as to update this colab or duplicate it and show case how annotator works? It would make my life a lot simpler! 🙏🏻

[onuralpszr]

@onuralpszr, you know you don't need to work on your fork. You can create branches directly in supervision.

Habits :=) I will use here more okey 👍 :)

Could you add this link to an example annotated frame in docs? https://media.roboflow.com/supervision-annotator-examples/circle-annotator-example.png In a similar way, we have done it for other annotators.

@SkalskiP I was going to ask that, awesome thank you !!

[SkalskiP]

No worries ;) let me know once you update it. ;)

@onuralpszr One more thing. I see that you marked it as Hacktoberfest task. I'm all in favor. Small question: do we need to do anything else? Do you need issue associated with the PR? Is there anything else we need to do to make that PR count to Hacktoberfest?

"hacktoberfest-accepted" is enough to make it count.

Awesome! In that case, merging! 🚀
