This example shows a simple, static Christmas tree illustration composed of three layered green triangular tree sections, a red circular ornament, and a brown trunk rectangle. The design is rendered directly as SVG elements within an HTML page, using a straightforward combination of `<path>`, `<circle>`, and `<rect>` tags. The file structure includes a separate `styles.css` to reset the page margin and hide overflow, while the `index.html` contains the inline SVG markup. The visualization is a basic, non-interactive graphic that relies entirely on manual coordinate definitions rather than any dynamic or data-driven plotting library.
