Hello HTML
This example shows a simple yellow circle with two smaller circles, representing a face, rendered in an SVG canvas at 960 by 500 pixels. It demonstrates the bare minimum integration of React 18.2.0 into an HTML document by loading the production UMD build from unpkg and logging the React object to the console. The rendering uses raw SVG elements—`circle` with `cx`, `cy`, `r`, and `fill` attributes—without any additional libraries or data sources beyond the static shapes defined directly in the markup.
