This example displays a large, centered “Hello VizHub!” message in bold Ubuntu font on a dark background. The visualization uses D3.js v5’s `select` method to set the text content of a `div` element, with the message imported from a separate ES6 module. The styling is handled via CSS, including Google Fonts for the typography and a simple color scheme. No data is loaded or transformed; the focus is on demonstrating basic D3 DOM manipulation and module structure.
