This example demonstrates VizHub’s ability to combine HTML, CSS, ES6 modules, and D3.js into a single interactive document. It renders a large, styled welcome message on a dark background using the Ubuntu font. The code imports the D3 `select` function to target a div and set its text content from a separate module, `myMessage.js`, which exports a string. Styling is applied via an external stylesheet with a Google Fonts import, and D3 v5 is loaded from a CDN.
