This example demonstrates a hand-coded collection of SVG shapes, including circles, rectangles, lines, and paths, arranged in groups with transforms and styling. It shows both static elements and a grouping of shapes with explicit fill and stroke attributes, as well as a second group using a CSS class to apply stroke styling. The code uses plain SVG within an HTML document, applying D3 only via the page title and structure; actual visualization is achieved through direct SVG markup and CSS, with no JavaScript-driven data binding or D3 API calls in the visible source.
