This example displays the text “Hello VizHub!” centered on a dark blue background using large Ubuntu typography. It demonstrates how D3.js version 5 selects a DOM element and updates its content, while also showcasing ES6 module imports for separating data and logic. The code imports the `select` function from D3 and a custom `message` string from a local module, then applies the text to the `#message` div. Styling comes from a CSS file that loads Google Fonts and sets the page’s color scheme.
