This example displays a single large “Hello VizHub!” message centered on a dark blue background using the Ubuntu font. It demonstrates a minimal D3.js setup, importing the `select` function to target the `#message` div and set its text content. The message string comes from a separate ES6 module, `myMessage.js`, while styling is applied via an external stylesheet. The code relies on d3.v5 and standard DOM selection methods, with no dataviz logic or data sources involved.
