This example demonstrates the fundamental building blocks of SVG rendering in a React application, using JavaScript and CSS to create a minimal interactive canvas. It showcases how SVG elements are structured and displayed directly within an HTML document, with a focus on the raw markup required for basic shapes and styling. The code relies on native browser APIs—specifically the SVG namespace and standard DOM manipulation—rather than external visualization libraries, and it references a React Starter template for comparison. The approach highlights the simplicity of starting with pure SVG before introducing higher-level frameworks.
