Hello HTML
This example shows a single yellow circle centered on a 960 by 500 SVG canvas, with a black stroke and a radius of 245 pixels. It is a minimal demonstration of how to embed SVG directly in an HTML page using inline CSS and JavaScript-free markup. The code relies on the SVG `<circle>` element and CSS properties for sizing and stroke styling, with the body margin removed and overflow hidden for a clean, full-viewport look. It illustrates the fundamental building blocks of web-based data visualization without any external libraries.
