This example demonstrates a minimal SVG circle rendered inside an HTML page. It uses the raw SVG `<circle>` element with an `r` attribute, centered by default. The code relies on SVG's built-in rendering capabilities without any JavaScript libraries. It shows that a basic visualization can be created with just a few lines of markup, using standard SVG tags directly in the document body. The circle is drawn with no fill or stroke properties, appearing as a simple outline.
