This example demonstrates that a minimal web document can use an SVG circle element to render a basic shape, though the circle is drawn without any visible positioning or styling. The single `index.html` file contains a bare HTML5 structure with an embedded SVG viewport, referencing the circle markup directly rather than loading external data. The rendering approach relies on the browser’s native SVG support, using the `<circle>` tag with only its `r` attribute set. The page functions as the simplest possible illustration of vector graphics in an HTML context, with no JavaScript libraries or interaction.
