This example displays a bold, full-screen text message, "Cars VizHub!", against a dark navy background using the Ubuntu font. It serves as a minimal demonstration of VizHub’s project structure, showing how an HTML page loads a D3.js script to manipulate the DOM. The code imports the `select` function from D3 v5 and uses it to set the text of a `#message` div, while a separate ES6 module exports the message string, illustrating modular JavaScript and stylesheet integration.
