This example demonstrates the fundamental building blocks of SVG rendering in a web page, using plain HTML and CSS with JavaScript. The code sets up a minimal document structure with an empty body, indicating a starter template for creating SVG visualizations. It shows how to initialize a basic webpage that can be extended with SVG elements and styles. The example relies on native browser APIs for SVG and CSS rather than external libraries, providing a clean foundation for learning SVG basics within a React or vanilla JavaScript environment.
