A minimal SVG drawing renders a yellow circle with a black outline as the main face, featuring two smaller circles for eyes and a curved path for a smile. The artwork is created directly in an HTML file using inline SVG elements, including `<circle>` for the head and eyes and a `<path>` with a cubic Bézier curve for the mouth. The page contains no JavaScript or external libraries, relying solely on static vector markup to produce a simple "Hello World" smiley face.
