This example displays a single text message, "Hello VizHub!", centered on a dark blue background using large, light-colored Ubuntu font. It demonstrates the basic structure of a VizHub project with separate HTML, CSS, and JavaScript modules. The code imports the `select` function from d3.v5 to target the `#message` div and set its text content, while the message itself is exported from an ES6 module (`myMessage.js`). It illustrates how to combine D3.js API calls with modular JavaScript and external stylesheets.
