This example demonstrates how to combine inline SVG shapes with CSS styling to create and transform basic geometric forms. It shows circles, rectangles, and paths, with styling applied through CSS selectors like `.lines` and `.lines path` controlling stroke color and join behavior. The SVG markup uses the `<g>` element to group shapes and apply transformations via the `transform` attribute, including scaling and translation. The code relies on raw SVG APIs and a cascade of CSS rules from an external stylesheet to define presentation details.
