This example displays a single yellow circle with a black outline, centered on a blank 960 by 500 pixel canvas. The visualization is built with an embedded SVG element inside a minimal HTML page, using the circle’s `cx`, `cy`, `r`, `fill`, and `stroke` attributes to define its geometry and styling. The page’s CSS removes body margins and hides overflow, ensuring the circular graphic fills the viewport without scrollbars. No external libraries or data sources are required, as the shape’s properties are hard-coded in the markup.
