This example demonstrates the fundamentals of SVG rendering with a static visualization of two primitive shapes: a firebrick-red circle and a steelblue rectangle. The code uses raw SVG elements (`<svg>`, `<circle>`, `<rect>`) positioned via `cx`, `cy`, `x`, `y`, and sized with `width`, `height`, and `r` attributes. The rendering approach is declarative SVG markup embedded directly in an HTML page, with no external libraries or data sources, relying on the browser’s built-in SVG support to display the shapes.
