Hello World!
This example displays a single yellow circle centered on a 1000 by 500 SVG canvas. It demonstrates the minimal structure for embedding SVG elements directly in an HTML page without any styling or scripting. The code uses standard SVG tags—`svg` and `circle`—within the body, specifying dimensions and a radius of 100. No JavaScript or external libraries are involved, making it a pure, static markup example. The rendering approach relies entirely on the browser’s built-in SVG support.
