A standalone SVG Christmas tree is drawn inside an empty `<g>` element, with the page layout controlled by minimal CSS. The example relies on the browser’s native SVG rendering rather than any JavaScript libraries or data-binding APIs, as the markup contains no dynamic elements or external data sources. The tree itself is a static graphic, shown at a fixed 960×500 pixel viewport, with the SVG’s internal coordinate system defining the shape. No interaction or animation is present, making the visualization a purely decorative, code-only illustration.
