This example displays a static yellow circle with two smaller black circles, forming a minimal smiley face. The data is hardcoded directly in the HTML file rather than loaded from an external source. The visualization uses raw SVG elements—specifically `<circle>` tags—with attributes for positioning, radius, fill, and stroke colors. The page embeds a YouTube video in an iframe, and the body style sets `margin: 0` and `overflow: hidden`. The rendering approach is purely SVG, with no JavaScript libraries or dynamic data processing involved.
