Hello
This example demonstrates the simplest possible start with D3 version 7, rendering static text in the browser. The page displays “Hello world” as a heading, then immediately replaces the body’s text content with “Hello D3 version 7” using the `select` method from the D3 library. The code loads D3 v7.8.5 from a CDN and uses `bundle.js` to execute the JavaScript, showing a minimal setup where a single selection and text assignment update the DOM without any data binding or visualization.
