This example shows a minimal SVG scene: a yellow circle outlined in black, with a smaller black circle inside it, centered on a 960 by 500 canvas. It demonstrates how to combine React with raw SVG elements in an HTML page. The code loads React via a CDN script and uses inline SVG tags like `<circle>` and attributes such as `cx`, `cy`, `r`, and `fill` to draw the shapes. No data is involved; the focus is on the simplest possible integration of React with the DOM and SVG.
