This example demonstrates that SVG elements can be rendered directly within an HTML page without any external dependencies. The code defines a single `<circle>` element with a radius of 100 units inside an inline `<svg>` tag, which the browser displays as a black circle. No JavaScript or styling is applied, so the circle appears at the default position. The example highlights the fundamental simplicity of embedded vector graphics, serving as a minimal starting point for HTML-based data visualization.
