This example demonstrates fundamental SVG shapes, using the `circle` and `rect` elements to create a simple static composition. The visualization shows two colored circles and a rectangle, each with explicit positioning and styling attributes. The code relies on native SVG APIs within an inline `<svg>` tag, setting `cx`, `cy`, and `r` for circles, and `x`, `y`, `width`, `height`, `fill`, and `stroke` for the rectangle. The rendering is direct SVG markup in the HTML, with no external libraries or data sources, highlighting basic shape construction and attribute-driven styling.
