This example creates a basic three-dimensional scatter plot visualization using D3 version 7.8.2. The code initializes a D3 selection on the HTML body element and renders the text "Hello D3 version 7" using the `select` and `text` methods. The visualization demonstrates the simplest possible D3 setup, where a static text output is displayed rather than an actual 3D scatter plot, despite the title. The HTML file loads the D3 library from a content delivery network and executes the JavaScript from an external bundle file.
