SVG formar
A single green circle with a thick yellow stroke occupies the center of an SVG canvas, filling its 100 by 100 pixel viewport. The example demonstrates fundamental SVG shape rendering within a React project, using plain HTML elements such as `<svg>` and `<circle>` rather than a visualization library. Styling is applied via a separate CSS file, which sets the page font and size, while the SVG attributes control the circle’s fill, stroke, and dimensions. The code shows a minimal static graphic with no interactivity or data binding.
