This example presents a minimal HTML page that renders a single SVG circle using inline markup. The code relies on the native SVG `<circle>` element with a radius of 100 and a center coordinate of 500,500. It demonstrates a bare-bones structure combining CSS and JavaScript in a single file, with an empty `<style>` block and no script logic. The visualization is static, showing only the geometric shape without interaction or data binding, serving as a starting point for building more complex React-based visualizations. The rendering approach uses the browser’s built-in SVG support.
