Hello World
This example, titled “Hello World,” shows a minimalist smiley face constructed from three SVG circles: a large yellow face with a black stroke and two smaller black circles for eyes. The rendering uses raw SVG within an HTML document, with all elements drawn using the `<circle>` tag and positioned via `cx` and `cy` attributes. The code includes comments referencing coordinate calculations, but the visualization itself is static, with no interaction or animation. It demonstrates basic SVG shape creation and styling without any external JavaScript libraries.
