This example displays a simple static composition of SVG shapes, including two outlined circles and two filled rectangles, arranged on a 500 by 500 canvas. The geometric figures are defined directly in the HTML markup, with styling applied through a CSS rule for a message class, though no text is rendered. The visualization uses inline SVG elements within an HTML page, and the circles are styled with a black stroke and no fill, while the rectangles appear with default black fills. No JavaScript libraries or interactive features are present; the code relies purely on native SVG and CSS.
