This example shows how to create and style geometric shapes using raw SVG and CSS within a React application. It demonstrates drawing multiple polygons, a line, and a path, with attributes and styles applied both inline and via a separate stylesheet. The code utilizes SVG elements like `<polygon>`, `<line>`, and `<path>`, and uses a `<g>` transform to translate a group of shapes. The CSS file defines a `.lines` class, applying stroke properties and rounding the path's line joins.
