This example displays a static SVG composition of geometric shapes: a green circle with a red stroke, a large blue circle, a small rectangle, two blue lines, and two black polygonal paths. It shows how SVG elements can be layered and styled via CSS, with the first circle receiving a distinct class-based fill. The rendering relies on raw SVG markup in `index.html` and uses React starter code commented out in `index.js`, indicating the visualization currently renders without React’s involvement. The layout is fixed, using explicit coordinates and pixel-based dimensions.
