Face part 1
This example displays a simple, static visualization of a yellow face: a single circle with a black outline centered on a light background. The visualization uses only an inline SVG element, with the circle’s position, size, and colors set directly via attributes like `cx`, `cy`, `r`, `fill`, and `stroke`. The page is minimal, containing no external JavaScript libraries or data sources, and the SVG is rendered without animation or interactivity.
