Shapes with SVG and CSS
This example shows how to draw basic SVG shapes—circles, rectangles, lines, and paths—within a React application using plain SVG elements and CSS styling. The SVG renders at a fixed width and height, with groups applying transforms to scale, translate, and position shapes. CSS classes, such as `.lines`, control stroke color and width, while inline attributes define fills like `red` and `#83CC2A`. The code uses React and includes a minimal JavaScript file that sets a text message, demonstrating SVG and CSS integration without a charting library.
