This example demonstrates the basic building blocks of SVG shapes—circles, rectangles, lines, and paths—styled through CSS. It shows how a group element can apply shared fill and stroke properties, while a separate class targets line and path elements for custom stroke width and color. The code uses plain HTML, CSS, and JavaScript within a React framework, rendering via SVG. The shapes are manually positioned with fixed coordinates on a 960 by 500 canvas, with no external data source.
