This example demonstrates a minimal SVG circle rendered inside an HTML page, using no external libraries beyond standard web APIs. The markup defines an `<svg>` element containing a single `<circle>` with a radius of 100 units, which displays as a simple black circle against the page background. The code relies on the browser’s native SVG support to render the shape, with no JavaScript, data binding, or interaction logic present. It serves as a foundational template for embedding vector graphics directly into web content, showing how raw geometric elements can be declared inline. The circle’s center defaults to the origin, so it appears in the top-left corner of the SVG viewport.
