A single yellow circle with a black outline is centered on a plain white SVG canvas. The example demonstrates the minimal setup for an SVG-based visualization using only vanilla HTML and SVG elements, with no external JavaScript libraries. The circle is defined with explicit `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width` attributes inside an `<svg>` tag sized 960 by 500 pixels. The page’s body margin is removed and overflow hidden to present the graphic without scrollbars.
