Hello VizHub
A simple text-display example demonstrates VizHub's project structure and module system. It imports the `select` function from D3.js and a custom `message` constant from a local ES6 module, then uses D3's `select` to write that message into a `div` element in the HTML. The page uses a dark background with light, large Ubuntu font text, rendering the single greeting "Hello VizHub!" centered on screen. No data is loaded; the visualization is purely a text output.
