This example demonstrates a minimal D3.js visualization that renders a static text message, “Hello VizHub!”, into a centered HTML div. It shows how to set up a VizHub project by loading D3 v5 from a CDN and importing both the `select` function from the `d3` module and a local ES6 module. The code uses `select('#message').text(message)` to update the DOM, with styling provided by CSS. It also includes a regular expression and variable declaration, though these do not affect the visual output.
