This example displays a simple greeting, “Hello VizHub!”, rendered as large, centered text on a dark background. It demonstrates a basic D3.js setup by using the `select` function from the d3 module to target a div element with the ID `message` and set its text content with a string imported from a local ES6 module. The page loads D3 v5 from a CDN and applies custom styling via an external stylesheet that imports the Ubuntu font and defines the body’s layout and color scheme.
