This example demonstrates the basics of SVG drawing with a simple red circle and a yellow rectangle on a blank canvas. It uses raw SVG elements (`<circle>` and `<rect>`) within an HTML page, styled by a minimal CSS file that removes default margins. The visualization serves as an introductory template for learning SVG syntax, with a fixed 1000×500 viewport and no interactive or data-driven behavior. A link to a React starter is included for further exploration.
