SVG Fundamentals
This example demonstrates the minimal setup required to render an SVG element in an HTML page. It shows a single red circle positioned at coordinates (50, 50) with a radius of 50 pixels. The code directly uses the native SVG `<circle>` element with `cx`, `cy`, and `r` attributes, embedded inside an `<svg>` tag. No external JavaScript libraries or data sources are involved; the visualization relies solely on the browser’s built-in SVG rendering of static markup.
