This example demonstrates how to display a static text message using D3.js and ES6 modules. The code imports the `select` function from D3 and sets the text content of a `div` element to “Hello VizHub!”. It also imports a local module to supply the message string and defines a regular expression and a numeric constant. The HTML loads D3 from a CDN, includes a CSS file for styling, and bundles the JavaScript within the page structure.
