This example demonstrates how to create basic SVG shapes—circles, rectangles, lines, and paths—using React and CSS styling. It shows both default black shapes and colored variants, with a specific group (`g`) applying a cyan fill and black stroke, while a `.lines` class adds thick green strokes with rounded line joins. The SVG canvas uses a scale transformation and translation to position elements. Styling is handled entirely through the linked `styles.css` file, with no JavaScript data manipulation, as the example relies solely on static markup.
