This example demonstrates basic SVG shapes and CSS styling, showing circles and rectangles in different configurations across a canvas. The first row uses default black fills, while the second row applies individual fill colors (pink and a green hex value) directly to elements. A third group applies presentation attributes like `fill` and `stroke` to multiple shapes at once, and a final group with a class selector (`.lines`) styles lines and paths with stroke properties. The code uses raw SVG elements (`circle`, `rect`, `line`, `path`) with transforms for scaling and translation, styled via an external CSS stylesheet (`styles.css`).
