Circle Sprite showing Square

I’m trying to create a circle shaped sprite in Unity for my graph as a dot/coordinate.
However it is showing as square! What did I do wrong?
I simply right click in my materials folder then select Sprite, circle.

 

As far as I know the procedurally generated Unity sprite primatives can only be used with a SpriteRenderer. They will preview as a white square as an asset, but the sprite subobject should show the shape in the inspector.

 

I started using the sprite in my script, using the following,

Code (CSharp):

1. [SerializeField] private Sprite circleSprite;
2.  
3. GameObject CreateCircle(Vector2 anchoredPosition)
4.     {
5.         GameObject gameObject = new GameObject("circle", typeof(Image));
6.         gameObject.transform.SetParent(graphTransform, false);
7.         gameObject.GetComponent<Image>().sprite = circleSprite;
8.         RectTransform rectTransform = gameObject.GetComponent<RectTransform>();
9.         rectTransform.anchoredPosition = anchoredPosition;
10.         rectTransform.sizeDelta = new Vector2(1, 1);//size of circle
11.         rectTransform.anchorMin = new Vector2(0, 0);
12.         rectTransform.anchorMax = new Vector2(0, 0);
13.         Debug.Log(gameObject);
14.         return gameObject;
15.     }

However, when it is created during runtime, it is showing as a square. Regardless of the size i set it to using,
rectTransform.sizeDelta = new Vector2(1, 1);//size of circle

 

You're using an Image component to display the sprite in the UI, but as I said I believe those it can only work when using a SpriteRenderer. You'll have to import your own circle sprite to use in the UI.
