This example demonstrates a simple SVG scene of a yellow circle with two smaller black circles, using React 19's development build loaded directly from unpkg. The code renders three circle elements within an inline SVG, with the main circle centered via percentages and the smaller ones positioned absolutely. The script logs the React object to the console to confirm the library has loaded, while CSS hides the body margin and overflow. The visualization shows basic SVG geometry and React integration without additional data or interaction.
