This example shows a minimal static SVG composition—a circle, a line, and a path—rendered with text reading “hello world” in the page header. The visualization renders directly through SVG elements defined in `index.html`, while `index.js` uses plain DOM manipulation (`document.getElementById`) to set the message. D3 version 6 is introduced via the README's embedded tutorial link, but the visible code itself does not call any D3 APIs. Styling in `styles.css` sets a monospace font and removes page margins, with the SVG output as the main graphic.
