A crescent looks as if another circle has bitten into one side of a round shape. Its moon-like silhouette is easy to recognize as an icon or directional accent.
`radius` sets the outer circle radius from 0.05 to 1. `innerRatio` is the inner circle radius as a fraction of the outer one, from 0.3 to 1.2. `offset` moves the inner circle horizontally from the center, from 0.01 to 0.5. Use `rotation` from 0 to 360 degrees to turn the crescent.
The combination of `innerRatio` and `offset` changes both the bite's width and position. Place it alongside `Circle` to compare the forms or add a `Star` as a backdrop accent, and check that its opening remains clear at small sizes.
When to use
Use it for moon icons, night themes, or directional decoration. Its bitten, asymmetric silhouette can guide attention. Avoid it when you need a closed circle or a symmetric circular band.
