SVG fundamental
This example demonstrates the fundamental SVG shapes by rendering two colored circles inside an SVG element. It uses plain SVG markup with `circle` elements, setting explicit `cx`, `cy`, and `r` attributes to position and size each circle, while `fill` defines their colors. The page loads from an `index.html` file with an inline SVG, supported by a separate `styles.css` for page styling and an `index.js` that logs a message to the console.
