SVG Fundamentals
This example demonstrates the absolute minimum structure for rendering vector graphics on the web, displaying a single black circle inside an inline SVG element. The code defines the circle’s position and radius directly via the `cx`, `cy`, and `r` attributes on the `<circle>` tag. It uses no JavaScript libraries or data sources, relying solely on native SVG syntax within a bare HTML page. The entire graphic is produced by the browser’s built-in SVG renderer, with the static shape defined entirely in markup.
