This example shows a simple React application that renders a yellow circle with a black outline inside an SVG canvas, accompanied by two smaller unfilled circles. It demonstrates how to combine React with SVG elements using ReactDOM.render() to mount the component. The code imports React and ReactDOM from UMD builds, defines a functional component that returns SVG markup with hardcoded attributes like cx, cy, r, and stroke-width, and inserts it into a root div. The rendering approach relies on React’s declarative JSX syntax to describe the SVG shapes.
