This example displays the text "Hello VizHub!" prominently in the center of the page. The visualization is created using D3.js version 5, specifically leveraging the `select` API to target a div element with the ID "message" and set its text content. The styling is handled through a CSS file that applies a large font size and center alignment. The code also includes an ES6 module export for the message string, along with some unused variables and a regular expression pattern.
