This example draws a static smiley face using only SVG primitives within an HTML page. It shows a large yellow circle for the head, two smaller black circles for the eyes, and leaves the mouth absent, creating an incomplete expression. The rendering relies on the SVG `circle` element with explicit `cx`, `cy`, and `r` attributes set inside an inline `<svg>` tag, with styling controlled via CSS and inline attributes. No JavaScript libraries or data sources are used; the visualization is purely declarative markup.
