This example shows a simple yellow circle centered on a black-bordered SVG canvas. The visualization relies solely on raw SVG elements, using a `circle` tag with explicit `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width` attributes. No JavaScript libraries or data sources are involved—the rendering is static and defined directly in the HTML markup. The page uses an inline SVG with a fixed 960 by 500 pixel viewport, and the body margin is set to zero with hidden overflow for a clean display.
