This minimal example demonstrates a single text element reading “HI” rendered at the top-left of the page. It uses D3v7’s `select` to append a `text` node to the body and set the `cx` and `cy` attributes. The code runs inside an asynchronous `main` function and loads D3 from the unpkg CDN, with a separate `bundle.js` containing the custom JavaScript. No data source or dynamic visualization is shown; it serves as a starter template for D3 projects.
