This example demonstrates a minimal D3.js setup that renders a single text message on a webpage. It shows how to structure a basic VizHub project with separate files for markup, styling, and JavaScript logic. The code uses D3’s `select` function to target a div element and update its content with a string imported from a local ES6 module. The page is styled with a dark background and large Ubuntu font, and it loads D3 version 5.9.1 from a CDN.
