This example displays the text “Hello D3 version 70” in the center of the browser window, rendered at an enormous font size of 13em. It demonstrates a minimal D3 v7 setup, where the `select` function from the d3 module targets the `<body>` element and sets its text content. The page loads D3 from a CDN and runs the JavaScript from a separate `bundle.js` file, highlighting a basic data-binding workflow.
