This example demonstrates basic SVG shapes and CSS styling within a small graphic. It shows circles and rectangles with inline fill colors, a grouped set of shapes with a shared fill and stroke, and lines and paths with custom stroke properties. The code uses raw SVG elements like `circle`, `rect`, `line`, and `path`, along with CSS classes applied to a `<g>` element for stroke styling. The rendering is entirely SVG-based, with a transform scale applied to the parent group.
