Shapes with SVG and CSS
This example demonstrates a collection of SVG shapes—including circles, rectangles, and polygons—styled with CSS properties such as fill colors, strokes, and opacity. The shapes are static and arranged on a blank canvas with no margins. The code uses D3 v5 only to load the page structure, while all visual styling is handled through an external stylesheet. The HTML includes links to the D3 library and CSS file, but the body remains empty, meaning the actual shape rendering relies on CSS-drawn elements not present in the provided files. The page sets `overflow: hidden` and removes default margins.
