This example combines React and SVG to display a simple static visualization of a yellow circle with two smaller circles positioned inside it. The page renders a basic React component that outputs the text “Hello Data” alongside the SVG shapes drawn directly in the HTML markup. React 18 handles the component rendering, while CSS resets the body margins and hides overflow. The visualization does not include any interactive or data-driven behavior, serving as a minimal starter template for integrating React with SVG graphics.
