This example demonstrates how VizHub projects are structured, showing a simple web page that displays the text “Hello VizHub!” in large centered type. The visualization uses D3.js v5, loaded via UNPKG, to select the `#message` div and set its text content. The project also illustrates ES6 module imports, both from the D3 library (`import { select } from 'd3'`) and from a local module (`./myMessage`), which exports the displayed message string. A separate CSS file styles the message with a 12em font size.
