Smiley face
A yellow circle with a black outline forms a smiley face, featuring two smaller black circles for eyes on a plain background. The example demonstrates basic SVG shape rendering inside an HTML page, using the `<svg>`, `<circle>`, `fill`, `stroke`, and `stroke-width` attributes directly in markup without any JavaScript libraries. The static visualization is created entirely with inline SVG elements, with no interaction or animation, and serves as a minimal introduction to drawing vector graphics in the browser.
