This example demonstrates fundamental SVG shapes and path commands within a bare-minimum HTML page. It shows how to construct graphics using SVG elements directly in markup, with commented-out examples of circles, a complex path with lines and curves, and an arc. The active code renders a single red arc path using the `M` (move to), `A` (arc), and coordinate parameters. The page relies on native browser support for SVG and CSS, with no external JavaScript libraries or data sources involved.
