This example displays a minimal HTML page containing an SVG with a circle and a green rectangle, demonstrating basic SVG rendering within a React project. It shows how primitive shapes can be positioned using `cx`, `cy`, and `r` attributes for the circle, and `x`, `y`, `width`, and `height` for the rectangle. The page is built with HTML and SVG, rendered directly in the browser. The code uses the React framework, with the SVG drawing defined inline in the `index.html` file.
