This example demonstrates a single SVG circle rendered on a blank page, serving as a minimal introduction to SVG shape fundamentals. The code directly uses the SVG `<svg>` and `<circle>` elements, with the circle positioned at coordinates (50, 50) and a radius of 50. No JavaScript libraries or data sources are involved; the rendering is purely static markup. The page includes a minimal HTML skeleton with an empty `<style>` block, showing the basic structure required for embedding SVG in a web document.
