A circle is the simple round shape behind things like status dots and profile badges, expanding evenly from its center.
`radius` controls its size from 0 to 2; 1 makes the circle fit the canvas. Move it with `center`, and raise `softness` from 0 to 1 for a softer edge. `strokeThickness` sets the outline width from 0 to 0.5, with 0 meaning no outline.
At its default size, the circle can take up most of the frame, so lower `radius` for a small dot. Place it over a background or pair it with `Ring` for a badge or target-like composition.
When to use
Use it for status dots, badges, avatar accents, or a simple circular highlight. It also works for target-like graphics. Avoid it when the shape needs different horizontal and vertical radii.
