This example shows a single gray circle centered on an otherwise blank SVG canvas, serving as a minimal demonstration of embedding Scalable Vector Graphics directly in an HTML page. The code uses no external JavaScript libraries or data sources; it relies only on native SVG elements within the document body. A `<circle>` element is positioned with explicit `cx`, `cy`, and `r` attributes, while the `svg` container sets the drawing area’s dimensions. The fork title references the original “Hello HTML” example, but the visualization itself contains no interactive or animated behavior.
