This example demonstrates a minimal SVG element within a plain HTML page, rendering a simple gray rectangle as the sole visual output. The code uses the SVG `svg` tag with `width` and `height` attributes to define the drawing area, while the `background` and `border` attributes—though non-standard—are included to style the shape. It serves as a bare-bones "Hello World" for HTML and SVG, relying on no external libraries or JavaScript. The page is a fork of an existing minimal HTML template, showcasing the simplest possible data-visualization container.
