This example shows a simple, static smiley face rendered as a blank HTML page with an embedded YouTube video. The page contains no visible visualization or interactive elements; instead, it relies solely on standard HTML structure without any external libraries or APIs. The rendering approach is minimal, with no canvas, SVG, or JavaScript-driven graphics present in the code. The only content is a title and an iframe, making the smiley face a conceptual placeholder rather than an actual data-driven graphic.
