Hello HTML
A minimal HTML page displays a solid yellow circle on a blank canvas, demonstrating the basic structure of an SVG graphic embedded directly in markup. The example uses no external libraries, relying only on native HTML and SVG elements, with a `circle` element positioned at `cx="480"` and `cy="250"` and a radius of `250`. The page’s `<style>` block hides margins and overflow, keeping the view clean, while the SVG renders without any interaction or data-driven logic. This serves as the simplest possible starting point for web-based visualization.
