This example demonstrates the minimal setup for a VizHub visualization, rendering a simple text message as the entire output. It shows how to combine D3.js v5, ES6 modules, and external styling in a single-page application. The code imports the `select` function from D3 and uses it to set the text content of a `<div>` element, while the message itself comes from a separate local module. The page’s appearance is defined in a linked CSS file, which imports the Ubuntu font and applies a dark background with large, centered text.
