This example demonstrates a minimal "Hello VizHub!" message centered on the page with D3.js styling. It shows how to load D3 via UNPKG, import functions such as `select` from the `d3` module, and import a local ES6 module (`myMessage.js`) to supply the text content. The code uses `d3.select` to target the `#message` div and set its text, with CSS controlling the large centered font size. No data source or complex rendering is involved.
