This example demonstrates the fundamentals of SVG rendering by displaying basic geometric shapes, such as green and red circles, alongside HTML text. It uses the native SVG `<circle>` element with explicit coordinate and radius attributes to position shapes, while the `index.js` file renders a large "Hello World" message with a circle via a JavaScript template literal. The code leverages vanilla JavaScript and inline SVG, with the container’s `innerHTML` set directly to combine styled text and vector graphics. The example highlights how SVG integrates with HTML for simple, declarative data visualization.
