This example displays a collection of simple SVG shapes in a React application, including circles and rectangles positioned on a 1000x1000 canvas with varied colors like green, yellow, brown, red, blue, and pink. The code directly uses the SVG API through JSX elements such as `<circle>`, `<rect>`, and `<g>` for grouping and translation transforms. It demonstrates basic static rendering of geometric primitives without any data bindings or interactions, illustrating how SVG markup is embedded within an HTML page styled with the `shape` class.
