A single yellow circle with a blue stroke sits centered on a sky-blue SVG canvas, demonstrating a minimal HTML page with inline CSS and SVG markup. The page sets its body margin to zero and uses the `overflow` property, though the value is misspelled as `hidden` instead of the valid CSS syntax. The SVG element is declared directly in the HTML with fixed width and height attributes, and the circle’s position and radius are set via `cx`, `cy`, and `r` attributes. This example shows basic SVG rendering without any JavaScript libraries or external data.
