Hello html
A large yellow circle with a black outline and two smaller black circles drawn as an SVG face demonstrates the basic building blocks of HTML, CSS, and JavaScript. The code uses plain SVG elements (`<circle>`) inside an `index.html` file, styled with a CSS rule for the body margin and overflow. This example shows how static vector graphics can be rendered directly in a web page without any JavaScript interactivity or data binding, serving as a minimal starting point for React-based visualization projects.
