This example displays a large, centered "Hello VizHub!" message in bold text. The visualization is built using D3.js version 5, specifically leveraging the `select` API to target the message div and update its content. The code imports a local ES6 module to supply the displayed text, demonstrating a modular JavaScript approach. The styling is handled through CSS, setting the font size to 12em and aligning the text in the center of the page. The example serves as a minimal demonstration of integrating D3 with HTML and CSS for simple text-based output.
