This example shows a minimal SVG circle rendered as a static, un-styled element within an HTML page. It demonstrates the simplest possible use of SVG markup directly embedded in a document, with no external JavaScript or data binding. The code uses only native browser SVG rendering for the circle, defined by its radius attribute, and relies on inline HTML structure. The circle has no fill or stroke specified, so it appears as a black shape by default. This serves as a starting point for building more complex visualizations.
