This example demonstrates a minimal "Hello, VizHub!" message displayed on a web page using D3.js v5. It shows how to import D3 functions like `select` from the library via UNPKG and leverage them to set the text content of an HTML element. The visualization also showcases the use of local ES6 modules, importing a `message` string from a separate file. The rendered output is a large, centered text message styled through a CSS file.
