This example demonstrates how SVG shapes—circles, rectangles, lines, and paths—can be styled and transformed using Cascading Style Sheets (CSS) alongside inline attributes. The visualization shows a scaled grouping of primitives, with some shapes inheriting fill and stroke properties from parent `<g>` elements, while others specify these directly. The code imports the `select` function from D3.js to update a message div, and uses SVG’s `transform` attribute for scaling and translation. CSS classes like `.line` apply stroke styling and path-specific properties, such as `stroke-linejoin`, to the rendered vector graphics.
