A simple SVG smiley face rendered on an HTML page, using two black circles for eyes and a large yellow circle outlined in black to form the head. The code is a direct fork of a minimal "Hello HTML" example, relying on static SVG elements with explicit coordinates and styling rather than interactive or data-driven features. It uses the native SVG API within an HTML file, with body margins zeroed and overflow hidden for a clean presentation. No JavaScript libraries or external data sources are involved; the visualization is purely declarative markup.
