This visualization demonstrates a minimal Hello VizHub template that renders a centered text message using D3.js. The page imports the `select` function from D3 and a custom ES6 module exporting a string, then sets the text content of a div element via `select('#message').text(message)`. It includes a regular expression variable and a CSS rule styling the message at 12em font size. The example uses D3 v5 loaded from UNPKG, with HTML, CSS, and JavaScript separated into individual files.
