Hello VizHub
This example demonstrates a minimal "Hello VizHub" application, displaying a large, centered greeting on a dark blue background with the Ubuntu font. The visualization is a static text rendering, not an interactive chart, using D3.js version 5.9.1 to set the text content of a division element via the `select` function. Styling comes from an external CSS file, with the message string imported from a separate ES6 module, showcasing basic module handling and D3 DOM manipulation.
